William J. Duffy

I’ve spent the last 18+ years defending people in Orange County courts who thought their lives were over after a DUI or domestic violence arrest. In that time, I’ve handled well over a thousand DUI and domestic violence cases, won acquittals and dismissals, and helped countless clients stay out of jail and protect their futures. When you hire me, you get a trial lawyer who knows how these cases really work in our local courts and who treats your case like it’s the only one on the calendar that day.

Before opening Duffy Law , I served as a public defender, handling serious criminal cases for people who had everything on the line and no one else in their corner. My first nine jury trials all resulted in not‑guilty verdicts, and I bring that same preparation, aggression, and calm under pressure to every DUI and domestic violence case I take. My practice is focused on Orange County criminal defense, with a particular emphasis on DUI, domestic violence, and related charges, so I know the judges, prosecutors, and unwritten rules that can make the difference in your case.”
