Great attorney and a good man

My charges were very serious and had the potential to disrupt my professional life and marriage. I consulted with 60+ attorneys in the bay area and formally retained and fired 5 defense attorneys. Then I met Adam. He is everything you want in a criminal defense attorney. This morning, Adam got all my charges dismissed. He helped save my professional life and marriage.

Adam will go to bat for you and make sure your case has the very best possible outcome. He even worked with a PI to gather evidence, meticulously documenting facts. He is at the top of his game and worth every penny!

Criminal Defense FAQ

Common questions about criminal charges and your rights

If you are arrested, you have the right to remain silent and the right to an attorney. It is important to exercise these rights immediately and contact a criminal defense lawyer as soon as possible. Do not answer questions or make statements without an attorney present.

Our firm handles a wide range of federal and state criminal cases, including drug offenses, white-collar crimes, violent crimes, sex crimes, DUIs, fraud, embezzlement, assault, robbery, and other serious felony charges. We specialize in complex cases requiring sophisticated defense strategies.

Federal criminal charges are brought by the United States government and generally involve violations of federal law, such as tax evasion, drug trafficking across state lines, or white-collar crimes. State criminal charges are brought by the state government and involve violations of state law, such as theft or assault. Federal cases are often more complex and carry harsher penalties.

A plea bargain is an agreement between the defendant and the prosecutor in which the defendant agrees to plead guilty in exchange for a reduced sentence or lesser charges. This can be an effective strategy in certain cases, but requires careful consideration of all options with your attorney.

If you are not guilty, the burden is on the prosecutor to prove the case beyond a reasonable doubt. Your lawyer will work to challenge the prosecutor's evidence and show that there is insufficient evidence to support a conviction. This may involve presenting evidence, cross-examining witnesses, and making legal arguments to the judge or jury.

Misdemeanors are less serious crimes that are punishable by up to one year in jail, while felonies are more serious crimes that are punishable by more than one year in prison. Felonies carry more severe consequences and can affect your rights long-term, including voting rights and employment opportunities.
