I am a trial attorney with over 20 years of experience. I have successfully defended thousands of clients, tried hundreds of cases to verdict, and obtained acquittals in matters involving homicide, robbery, rape, drug trafficking, firearms offenses, repeat drunk driving, and nearly every other type of serious crime.
As a former prosecutor with the Bristol County District Attorney's Office, assigned to the Homicide and Major Felony Units, I gained invaluable insights into the real-time tactics, strategies, and methods employed by law enforcement and prosecutors during criminal investigations. This experience has significantly enhanced my criminal defense practice.
