Jeffrey M. Trissell




Mr. Trissell obtained his law degree from the George Washington University Law School in 2013. When he attended, it was ranked in the top 20 of law schools nationwide by U.S. News & World Report. Prior to that, he graduated magna cum laude from Oklahoma State University. He passed the California bar in 2013 and has been practicing law in San Diego ever since. He is admitted to practice before the Supreme Court of California, the Ninth Circuit, and the United States Supreme Court. He has also appeared pro hac vice in the Western District of Washington.

The majority of his practice is in high-profile constitutional law cases and in appellate work. He has handled many appeals in both California and federal court. In California, he has handled appeals in the Second, Fourth, Fifth and Sixth Appellate Districts. Many of his appeals have also resulted in published opinions, including in the Fourth and Sixth Appellate Districts and the Ninth Circuit. He has either personally drafted or edited six United States Supreme Court amicus curiae briefs, and he has worked on two United States Supreme Court petitions for certiorari. The rest of his practice is focused on general civil litigation, including serious personal injury, business disputes, and homeowners’ association disputes. He represents both plaintiffs and defendants in his practice. In his career, he has so far participated in three trials—including a month long-trial. He is active in local bar associations and is the Secretary of the St. Thomas More Society of San Diego, a bar association for Catholic attorneys.
