As owner of the Law Office of Matt Sullivan, Mr. Sullivan has extensive litigation experience in complex criminal defense matters. He began his legal career by working as a deputy public defender in the Marin County Public Defender's Office. As a deputy public defender Mr. Sullivan handled hundreds of criminal cases. Despite limited resources he was able to win acquittals, hung juries, or dismissals in the majority of cases he tried while at that office.

Mr. Sullivan then went to work for a private criminal defense firm in San Francisco where he was assigned primarily to work on serious state court criminal cases, including 3 strikes cases, and complex federal criminal cases involving drug conspiracy and violent crimes. While at the private criminal defense firm, Mr. Sullivan continued to consistently provide excellent results for his clients. Notably, Mr. Sullivan was second-chair trial counsel in a complex sexual misconduct case, where client was facing 50 years to life if convicted. After years of litigation, there was a 4-week jury trial in this case, which ended in a mistrial. The client was ultimately released from custody and returned to his family.

Following his work with the private criminal defense firm, Mr. Sullivan founded his own firm in San Francisco dedicated to client satisfaction, zealous advocacy, and providing superior legal services to his clients. The firm has achieved successful results for many clients. Mr. Sullivan has handled numerous cases involving complex forensic evidence, including DNA, toxicology, biomechanics of injury, false confessions, eyewitness memory, firearms and gunshot residue, computer and digital forensics, and accident reconstruction.

He earned his law degree from the University of San Francisco Law School where he took several courses in criminal law and procedure. In the practice area of criminal defense, Mr. Sullivan was selected by Super Lawyers Magazine to the Northern California Super Lawyers list for 2018-2023, and to the Rising Star list for 2013-2017.

Client Reviews
Mr. Sullivan helped me out during a very difficult time for me personally, and I am very satisfied with the outcome. He, unlike other attorneys that I spoke to, wasn't dramatic or falsely enthusiastic, and that was reassuring. He was savvy and realistic, experienced, a listener, flexible and affordable. D. Client
Over the past two years I have experienced extreme legal difficulties. We were unable to get help from anywhere. Within 24 hours of contacting Matt, I felt that I had finally found someone who could assist me in working towards resolving our situation. I highly recommend Mr. Sullivan. B. Client
I hired Mr. Sullivan to represent me in my DUI trial. He fought hard for me in a very difficult case, which we won. I was very happy with his services. It was obvious he cared about me and my case. He is a real attorney who will stand up for you. M.R.
