Client Reviews

Winning Lawyer

Adam represented me in three felony marijuana cases and each time the case was dismissed after Mr. Gasner's investigation showed the DA that I was a medical marijuana user.
In the most recent case, Mr. Gasner was successful in getting the SFPD to return 7.5 pounds that they had seized from me. This is the largest return of marijuana in California since Prop. 215 was enacted.
Adam is the most creative and diligent attorney I have ever used. He KNOWS how to win.
He also had my DUI in Napa dismissed!

Great help when in need!

I had a situation with the law quite some time ago, causing much stress and worry. The first thing I did was to look for a good defense attorney. After interviewing a couple of attorneys, I came across Adam Gasner. The fact that Adam was local to SF, very familiar with the local judicial system and genuinely concerned about my situation, convinced me to retain Mr. Gasner. I made the right choice. Mr. Gasner kept me well informed, made sure that I understood all of my options, and was not afraid to fight in court on my behalf. The outcome was very favorable. Thank You Mr. Gasner for helping me through my difficult times.

Thank you

Adam Gasner was a real professional and he kept me informed about every step of my case.

The best lawyer in California

Adam's courage, integrity and love of the law caused the dismissal of felony drug charges against our son. This was not an easy case with our son's prior convictions. Through out the process Adam communicated clearly and respectfully, anticipating the psychological storms that exist in this process. Anyone lucky enough to have Adam Gasner as their attorney can rest assured they will get the best possible outcome.


I hired Mr Gasner one year ago, as a referral from a very credible source in San Francisco. My case was particularly difficult to manage from a political perspective. Mr. Gasner handled the case with the utmost professional character, reliability and through judgment and patience had a more than favorable outcome. Unconditionally, I recommend Mr. Gasner for any case he would be willing to handle.

Adam Gasner works magic.

Before I consulted Adam, I was in bad shape. I was facing a felony charge, with a hand full of misdemeanors to go along with it. Usually in these situations one will end up in jail, or at least on probation with drug classes to coincide. Adam Gasner took my case and against incredible odds got all charges dropped! What did I have to do? 25 hours of community service. Finding Adam was the best thing ive ever done.

I can highly recommend Adam and am very happy with outcome of my case.

The outcome of my case could not have been better. Adam was excellent to work with and I am thrilled with the resolution of my case.

Maximum results

Mr. Gasner, a lawyer my youngest sister researched and found for me when, though I thought I was protecting myself, SFPD determined that I was the aggressor. A day and a half of time in jail, and meeting with another attorney the odds of dodging any kind of charge were looking bleak. Several hours later, I was able to meet with the attorney my mother and wife spoke so highly of, and with due right. I was truely amazed with the actual concern and compassion that came across the table as Adam began to ask about the events of that evening.

Adam is a great attorney

I found myself in a very tough legal prdicament last fall and was facing felony assault charges. I was put in touch with Adam by a friend. Within a few hours Adam was meeting with me (while I was still in processing at Bryant). I immediate felt comfortable with Adam. There is a very real, human quality to Adam and I got the sense he cared about my case.

The best possible outcome

Adam handled my shoplifting case. Although there were a number of factors that could have complicated the situation, I ended up with no criminal record. My overall experience with Adam was excellent and I would definitely recommend him. He is knowledgeable, professional, punctual and has made this whole thing much easier to deal with.


Adam got my charges acquitted on a 1 in a million chance in trial. He's the best lawyer I have encountered.

D.U.I Defense Attorney

Mr. Gasner was a great help. He was quick and responsive, prompt in returning my calls and following up with questions. He was able to negotiate an excellent deal for me. As an alternative to jail time for my offense, I was able to serve my time at an inpatient recovery program. I spent additional time at this program and Mr. Gasner asked the judge if the additional time served at treatment could be applied towards my court fee’s – which was granted. My sentencing was also greatly reduced by Mr. Gasner, as was, community service time.

Highly Recommended

I was faced with a double felony drug case with Adam and the charges were lowered to a single misdemeanor. Adam then got me into the Pretrial Diversion Program that ultimately led to my entire case being dropped. Adam is an absolutely terrific lawyer and I would highly recommend him to anyone who finds themselves in a similar situation.

Felony Drug Possession overturned reduced to a misdemeanor and released.

Our son was a student at SFSU in the spring of 2010. He was charged with felony possession. Adam was able to have the charge reduced, and eventually released with community service. Adam was straightforward with us as parents and with our son. He understood the situation and what needed to be done to address the charges. Adam was easy to deal with, straight forward and was very easy to stay in contact with (we live in L.A.). His follow up was excellent and I would highly recommend him.


Adam was very experienced in my case and clearly explained all facets of what could happen. He followed up and made sure everything was completely taken care of, even many months after the actual hearing. He was easily accessible including on the weekend.

thanks for the appeal...

i really wants to thank you for your service and help , everything when all right , my record is clean and i want to thank you again sincerely R.G.

Miracle worker!

Adam managed to get my felony DV charge dismissed in a politically fraught environment prior to my preliminary hearing. The charge, which stemmed from false allegations following a separation from my partner, was emotionally exhausting and was greatly impacting my ability to secure a job, income, and take care of my family.

Excellent Representation

I contacted Adam for help with a criminal defense case. He clearly laid out the options I had available to me, explained the legal processes that needed to be followed and got me the result I was looking for.

Very satisfied client !!!!

Adam's, expertise,knowledge and compassion were outstanding. He kept us updated on the case status even during the very busy times of his day. He know the "ins' and "out" of how the wheels of justice turn in SF. He was always honest and sraightforward in his communictions with us. He won an incredible victoty for our son even with the odds stacked agaisnt him. Adam is the best !

Highly recommended!!!!!

The moment I met Atty. Gasner I knew that he would
Take care of my case. I honestly felt no judgment if
I made or commited a crime or what not. He treated me with
compassion and professionalism. There's a lot of things
To say but if anybody is in need of a very good and reliable
Defense Atty. I would look no further. Regarding my case?
It was Dismissed! Thanks so much Atty Gasner


Adam Gassner is an intelligent, knowledgeable, calm, affable gentleman and I mean it!
Adam helped my son get into a rehabilitation program, and out of custody.
We are very grateful for Adam's great work.
Not much more to say - great work - .

Best Defense Available

I hired Adam years ago after dealing with several attorneys who, needless to say I wish I'd never gotten involved with. Adam came highly recommended from a friend of mine and client of his, who Adam had just defended and literally saved his future. Adam went to work immediately, getting a deal that was too good to pass considering the possiblity of real time and huge fines.

Excellent Lawyer

Adam was knowledgeable, responsive and most importantly, someone I trusted. I would absolutely recommend him to anyone in need of an excellent lawyer.

Thank you for your help!

I was so pleased with Adams great concern for my case in the short time I got to meet him at our consultation. I felt so lost and he help ground me and assure that if we needed to fight to the end he will do so. Thank you so much for your great wisdom Adam !

Professional, efficient, and results-driven

Adam responded to all of my questions in a timely manner. His experience, knowledge, and relationships in the San Francisco community helped to achieve the best possible resolution of my legal matter. Highly recommend.

Superior Advocacy

Adam Gasner is truly a next-level attorney. His knowledge of criminal defense is immaculate, and he advocates for his clients with the utmost compassion and professionalism. I learned more in my consultation than any other attorney has ever attempted to communicate to me. If you are seeking insight into a criminal case, Adam Gasner will prove a venerated oracle. If you are under criminal investigation he may just save your life!

Excellent Defense Attorney

Adam came highly recommended by both a family member (a lawyer at the San Francisco Public Defender's Office) and by a colleague of his (who did not handle federal cases). Although my case was relatively straightforward, the U.S. District court system is not. Adam was an expert in navigating through all of the minutia of the federal courts. He personally knew the Assistant U.S. Attorney and all of the judges, so I always felt like I was on the insider track. During the case, he thoroughly prepared me for each step in the process and I was very pleased with the outcome of the settlement.

Adam Gasner is great!

Adam Gasner was of tremendous help when I approached him with my case. When I first contacted him by phone, I knew right away that Adam was knowledgeable and would help me with my case. He is straightforward and comforting. Although my encounter with Adam was brief, from this point on he will be my go to guy when I need a lawyer. Don't hesitate to call him if you need a lawyer to represent you. You won't be let down. He has a 10 star rating on Avvo for a reason!

Professional, patient and resourseful.

After my arrest, Adam came highly recommmended from a friend at a top criminal defense firm in SF. My friend said it was important to hire someone that knows the laws and judges/courts in your county.
I can't express how happy and grateful I am to have hired him. He was patient and calming every step of the way and very resourceful in working around my needs. As a grad student, I was concerned about the effect the case would have on my scholarship and pending job hunt. After a thorough investigation, he was able to delay the conviction for 6 months until I'd graduated and been hired. And he worked wonders with the judge! Got an excessive BAC charge stricken and only minimum sentencing.

Excellent DUI attorney

Adam handled a very scary situation for us with warmth, compassion and extreme competence. He was the ultimate pro, guiding us through very unfamiliar waters. My case started out as a 2 felony count DUI with child endangerment (due to my child and a friend in the car) - that was reduced to a standard misdemeanor DUI because of his expert handling. Thank you Adam.

Thank You Mr. Gasner!

I got pulled over for a DUI while returning form my engagement party in the wee hours of a Saturday morning. I went through a very rough weekend since a DUI would impact my job, my immigration and everything else. A week's worth of research/meeting other lawyers and I finally landed at Mr. Gasner's office. He heard me out patiently, empathized with me and at the end of it concluded that we have a strong case and gave me insights as to how the whole case would proceed. He helped me handle the formalities at the DMV and got me set for the DUI classes as well.

Criminal Defense Client

I recommend Adam without reservation. I received his name from another lawyer who stated Adam would be better suited to help me based on the complexity of my case. Aside from being honest and professional throughout every step of the process, I can confidently say Adam honestly cared about my situation and well being. He eased me enough before every hearing, but also did not keep me in the dark. It was clear to me that Adam is a respected man/lawyer in the courtroom based on his interaction with the prosecution and judge.

Committed, Personal, Knowledgeable

Adam represented me in a criminal case for 2011. Without him, I would have lost my mind. His commitment to keeping me informed, and following up on open items was 1st rate. In the end, everything worked out, and I have no complaints.

Consummate professional. Goal-oriented advocate for your case.

With Adam's expert help, my DUI case was dismissed. He dilligently reviewed all aspects of my case and presented an intelligent, compelling argument in front of a judge and jury. I appreciated his knowledge of DUI laws, integrity, and responsiveness to my calls and email messages. He tirelessly worked on my case not only during office hours, but also on some weekends and evenings. My trial put my job at risk-- and Adam's compassionate and effective professionalism has helped me avoid any charges, and keep my career. I could not be happier with the outcome of my case. I would recommend Adam to anyone facing DUI charges.

Highly recommended

I have dealt with Adam twice now over a period of about 8 years, and while the fact that I had to come back is unfortunate, his handling of both cases, professional attitude, knowledge of the court staff and processes has been impressive. The process can be scary and confusing and he has kept up with the laws and always maintains a calm demeanor in guiding one through the steps.
I would recommend Adam to any client in the Bay Area needing DUI defense.

A tireless advocate -- trustworthy, dedicated, compassionate, an expert

I was fortunate to have Adam Gasner represent me in a criminal case stemming from a neighborhood dispute. Although he was not able to obtain the best possible outcome (dismissal) his knowledge, professionalism and strategic approach resulted in the charge being reduced from felony to misdemeanor, with the ultimate outcome being an expungement and a termination of probation.
From the first time I met with him until the day we shook hands outside the courtroom at the end of the legal process, he was a beacon of light during what was a very dark time. He was optimistic but realistic, calm and reassuring, thorough and personal (he visited my home to discuss the case with my wife and I as well as analyze the location of the incident), applied a strategy that was both aggressive and tactical, kept me updated on the process throughout -- ultimately allowing me to put my life back together and continue on as a husband, father and professional.
In life, perhaps it's better not to know a good lawyer -- if only because that suggests there is one less complication -- but I'm glad that I do know a good lawyer, one of the best any client could hope to have.
I recommend Mr. Gasner without any reservation.

Great DUI/criminal attorney

Adam Gasner came highly recommended to me from a friend after I was charged with a DUI. Adam sat down with me and went over the facts of my case and walked me through the entire process including the separate DMV and SR22 matters. After my initial conversation with Adam, I definitely felt better about the entire process and knew that Adam would assist me in getting the best results possible. Adam was always responsive to my questions and kept me informed as to his on going investigation. Adam is very respected among his peers and the staff of the courts which I strongly feel gave me an upper edge in how my case proceeded. In the end Adam was able to negotiate a great plea bargain for me and I was thriled with the results. Although we both felt I had a very good case to take to trial (and would have had complete faith in Adam handling the trial), the plea bargain was too good of an offer to pass, and I am confident that offer would never have been made without Adam's assistance.

One of the most professional lawyers in California!

Prior to visiting Adam, I had made a number of visits to other attorneys who I found to be unprofessional and seemed uninterested in my case. After meeting with Adam, he was the exact opposite. He had a professional demeanor and really listened to what I had to say and was genuine about helping me. Throughout my case, Adam was prompt with my inquiries via email and phone and alerted me as soon as there was something new. He comes highly recommended from me.

Very Good at His Job

I hired Adam many years ago to defend me in a case where I had been apprehended by the US Marshall's office for a misdameaner charge that had occured on federal land. Within a few telephone meetings he called me and announced the DA had dropped charges because of lack of due process, the incident had occured in 1995 and they came to arrest me in2005. I beleive that if I had not hired him there would have been a strong chance of a conviction with a Public Defender. He argued for me that I had not been in hiding so why did they wait 15 years to come get me-the DA didnt have a good reason and agreed to drop the charges. You can't ask for more than that! Thank You Adam-

Undoubtably the Best - Federal Criminal Defense

I was looking at a fourth DUI - this time in federal court carrying a one year prison sentence. Prison would mean losing my business, having to lay off several employees who depend on me, and missing out on baby girl's first year of life. Adam not only vigorously defended my legal interests, but he also represented my true personhood. He (and his staff) made themselves readily available for my questions and truly cared about my future. In court he was clearly respected by all the "players" and was well versed on the law. Needless to say, no prison or jail/custody time! I recommend Adam without hesitation.

Excellent Attorney

Adam Gasner was a great attorney to work with. After contacting multiple attorneys both over the phone and online, he was the first to respond back.

Sometimes in life you get truly lucky and get more than you pay for!!!!

Finding and contracting an attorney for representation can be an extremely daunting and stressful task, especially when initially dealing with your own legal challenges. Where does one start? Fortunately, research on the internet and AVVO proved that the internet can provide a true treasure when seeking competent and compassionate legal representation. I did not expect to find an attorney who is not only highly skilled and experienced with the criminal defense process and system but is also genuinely a caring and supportive individual.
The ultimate outcome of my situation far exceeded my initial expectations and based on the actual charges at the beginning of the process, I now can continue with my life and work without any significant interruptions or with a felony on my records. Kudos to Adam Gasner, I would recommend him to anyone, anytime!

Adam Gasner is the lawyer for you

Adam truly helped me in a time of need and I am forever grateful to him.
He answered my call in his car on the way to court and met me in the same day so he is very responsive and trustworthy and extremely knowledgable.
I would recommend him to anyone and have done so over 10 times in a week since we met.
If you have any worries, he will ease your mind almost as soon as you meet him.
If you need a criminal law lawyer, Adam is your man.
He is amazing and I will continue to promote him

Highly Recommend

Adam was very personable, instantly likable and made me feel at ease with a process of which I knew next to nothing, having never been i any sort of legal trouble before.. He was able to diagnose my domestic violence case immediately and give me multiple scenarios that could happen along with solid plans for each of them. And he was dead on about his prediction regarding the outcome of my case.

ADAM GASNER is a LIFE Saver and he DElivers!!!!!!!!

Got in trouble for 5 felonies that involve an "assault weapon." One of my best friend recommended me Adam and he was the many lawyers I was interviewing. I don't know what it was but Adam's vibe and experience put me at ease. Fast forward to 8 month's of negotiating with the judge and district attorney my case got reduced to one felony. And that can be reduced to a misdemeanor in a year for completing my probation and staying out of trouble. Overall I am very satisfied that I am able to get back on my feet and get on with my life and career!


Let me first start off by saying, I was facing years in state prison And i learned that you get what you pay for especially with legal defense so that bieng said mr Gasner took the time to review every aspect and nook and cranny with in the justice system mr gasner negotiated a deal for me that will result in a jail alternative which is hard to attain bieng said i had a prior felony. So im glad i trusted my gut instinct and selected him to represent my case

A true expert, with both a professional and creative approach

Adam came highly recommended by a lifelong friend. His firm grasp of the legal issues at stake, combined with his candor, gave me instant peace of mind. Adam approached the entire process with professionalism and creativity, and was never out of reach. In addition, his personal relationships with others in the community provided a valuable edge. Highly recommended.

Great laywer for first time offenders

I made a mistake and got charged with a misdemeanor in Federal Court. Adam helped me get the charge off of my record with the federal prosecutor with no mishaps. Adam was quick to respond to my e-mails or phone calls and I would highly recommend any first time offender to seek his help.

Best lawyer

Adam is an amazing lawyer. He is very personable and professional. My case was a very long and drawn out case, but Adam always kept up with everything and I was always well informed. I really appreciated that he would take the time to fully explain his thought process/strategy and was never condescending. Even though this was a stressful time, Adam made it a great experience and took care of everything.

Dignity and Respect

My son was arrested for possession of a controlled substance with intent to distribute. Not living in the area, I faced the daunting task of hiring an attorney long distance. I am so grateful that I came across Adam. His follow up and communication was excellent in keeping me informed every step of the way.

Responsive and results-driven

I had an unusual situation that required me to provide (within 30 days) specific documents relating to an arrest several years ago. For various reasons, the requested documents did not exist so the usual document request procedures through the Court would not have worked here. I needed an "out-of-the-box" approach to gain documentation that would satisfy the original request.

A Legal Brawler who Fights for Your Rights

Adam Gasner is legal rock star and a class act! He is a five-star criminal defense attorney and someone you want on your side when faced with serious legal consequences. I was charged with several felonies and I was tried not only in the criminal courts but also in the media given I was a public official. Notwithstanding the many challenges and obstacles he encountered fighting for my due process, Adam was confidently persistent in identifying and resolving several critical litigation issues and he worked collaboratively with the Court to ultimately expunge this matter. Trust me, Adam’s professional attitude, intense focus and dedicated commitment on my behalf made a huge positive difference in the end. Thank you Adam!

Highly recommended

I consulted with Adam about a case and found him extremely professional, reasonable, respectful and generous with his time. I regret not hiring him. I hope I am never in a position to need a criminal defense attorney again, but if I am, I would hire him immediately. I would recommend him without hesitation to anyone else in need.

Dui Case

After getting charged with a DUI, I began working with another lawyer that basically told me (after I paid him) that there was no hope in fighting the DMV because they never drop cases and the best I could hope for was a wet and reckless. My job was on the line so i went to Adam at the recommendation of another lawyer. Adam went above and beyond fighting the county, resulting in a dry and reckless, most importantly the DMV case was dropped. I was able to keep my job. I would definitely recommend him.

Trustworthy, Professional, and Thoughful

My experience with Adam was great. There was an emotional burden on my family and I, this sense of no way out and distress. My father had many sleepless night over my younger brothers case. We went to another county's court two times before finally getting a court date. Adam, luckily was there and gave some some thoughtful advice. He stepped in when he didn't have to and took it upon himself to help my family out. In the ensuing week my father was sleeping more and I was feeling a lot better about the whole situation. Reason I focus on emotion is because that is an area that reviews lack. His assistant John was very helpful as well, thorough and always responsive. I highly recommend Adam and his team to help you in your time of need.

Absolutely the best lawyer in San Francisco!

If you don't hire Adam Gasner to defend you, you're making a big mistake! I actually had hired another very well known, highly respected SF DUI lawyer and ended up substituting in Adam, and thank GOD I did. My daughter had gotten a DUI in SF and was also charged with assaulting a police officer. If that wasn't bad enough, her blood count was over 2.0 which is really bad. The other attorney really did nothing at all except make a couple appearances. That's it. He advised us there was nothing more to do until the DA filed the charges and notified us of the court date. That's the last time we heard from that lawyer. My daughter got pulled over for a traffic ticket and was arrested on the spot. There was a warrant for her arrest and we knew nothing about it. Long story short, I luckily heard about Adam and replaced the other attorney right away. Adam immediately went to work for my daughter and calmed her down and assured her he would take care of her. Did he ever! Somehow, he managed to get every charge completely dismissed! No plea bargain, no reduced sentence, etc. He got her off scot-free and every charge was thrown out and dismissed. He's a miracle worker and you will NOT regret hiring him to represent you. I guarantee it! He really is the best there is!

Truly a 5-Star Attorney

Adam Gasner indeed is a world class attorney. In my criminal case, I was accused of a felony charge which ended in being dismissed. That's the short story. However, the success is attributed to Mr. Gasner ability to seek the truth and presented the facts in court. He is very methodical, smart and very important to us clear in communicating options and expectations. Concise and accurate communication of facts and potential outcomes gave us peace of mind during this proceedings. You really can't put a price in knowing that you have hired the BEST lawyer. Mr. Gasner is an expert in his field and every well respected both in and out of the courtroom. I hope to never have to hire him again, but in the unfortunate event of having to do so; Mr. Gasner is my go to Lawyer.

Great Lawyer/Adam Gasner

Adam Gasner was fantastic and helped our family out immensely! He explains things in a manner that is easy to understand and is honest in letting you know what the outcome may be. He is not pricey and willing to work with you, very fair.

Highly competent, smart, well respected in the court

Adam helped me out with a fairly straightforward DUI case. I interviewed many different attorneys before choosing Adam, but ultimately the choice was easy. DUI legal defense can be a bit of a racket; some of the lawyers I spoke with used scare tactics to try and convince me that I needed to mount a vigorous and expensive defense, that I needed to decide on an attorney immediately. Adam took a different approach and just gave a lot of very helpful advice and took care of the case with ease. The fact that he is respected in the court and could be trusted to give me unbiased advice was well worth my investment. I could see that his capabilities weren't really being tested by my relatively simple case, and if I had a much more complicated problem, he would also be an excellent choice.

When it really matters.........

I like to keep things short and to the point. I made a wrong decision upon my visit to the city and my life was suddenly turned upside down.
I was being charged with a serious crime and I didn't know who to turn too. I live two hours out of San Francisco and I couldn't turn to friends and family because I was embarrassed of position with the law.
So looked at various websites and read peoples reviews. There was just some debts to the reviews I read regarding Gasner Law Firm.
I made the call and Spoke to John a Paralegal within the firm. Right from the beginning I received a warm comfortable feeling like someone really cared about my traumatic experience. ? All I have to say is this is a firm I wish I never have to ever use again but I would recommend them to anyone that needs a good and honest firm to take of what matters and that's you or a love one.
