Your liberty is at stake—we’re here to help.

If you have been charged with a crime in federal or state court, you have an understandable amount of anxiety and a myriad of questions. Your liberty is at stake. We’re here to help you understand the nature of your legal situation and form a plan designed for success. Our firm prioritizes client service, which often means crisis management. We understand that a criminal defense problem can have a ripple effect in a defendant’s life—even an arrest can cause irreparable collateral damage. Having the right counsel is critical. We have the experience and approach needed to mitigate the devastating effect a criminal charge can bring.

Our firm represents criminal defendants in state and federal courts from their first appearance through trial and on appeal. We litigate a broad range of matters, from complex criminal matters, such as heath care fraud and insider trading, to misdemeanor and violent felony offenses.

If you are being investigated, time is not on your side.

If you have been served a subpoena for documents, bank records or testimony, or otherwise believe you are the target of Government investigators, please contact us today. Government investigations require the right plan of action, which can only be carried out by experienced counsel. Do not take it upon yourself to comply with a subpoena or speak with investigators on your own. Our firm’s primary objective is always to avoid government investigation and criminal charges, when possible. Where this is not possible, we work to resolve the matter quickly and discreetly. We understand that civil and criminal investigations often affect each other, and work toward dispositions that favorably resolve both.
