About Our Practice
Experience Matters
Duffy Law PC (DLPC) was founded in 2017 by William J. Duffy, an experienced criminal and DUI defense attorney based in Orange County, California. Bill’s legal journey began as a law clerk at a small civil firm in Kalispell, Montana.
He went on to earn his law degree from WSU College of Law, where he also gained valuable experience as a certified law clerk with the Los Angeles County District Attorney’s Justice System Integrity Division.
After passing the California Bar, Bill served as a public defender in San Bernardino County—winning acquittals for his first nine trial clients before juries—a testament to his early dedication to justice.
Over the next decade, he honed his expertise at several leading Southern California law firms. These varied experiences gave him deep insight into the business of law, yet he remained driven by a desire to make a meaningful difference in people’s lives.
Guided by his faith, Bill felt called to use his legal skills to serve those seeking justice and redemption—whether they are victims of crime or individuals facing accusations. This sense of purpose became the foundation of DLPC, where every case is approached with compassion, integrity, and relentless advocacy.
With over 18 years as a criminal defense attorney—including more than 20 jury trials and countless court appearances—Bill brings both seasoned expertise and a heartfelt commitment to each client.
At Duffy Law , experience and purpose come together to provide you with steadfast defense and support when it matters most.
