“I defend people who have been charged with any felony or misdemeanor in both the state and federal courts.

As I have done throughout my career, I'll bring energy, experience and commitment to your defense. The primary focus of my practice is in the area of criminal law and criminal justice reform. As a former prosecutor, I have the knowledge and experience to quickly assess a criminal prosecution and to anticipate a police officer’s or prosecutor’s next move.”
