About David
Before he entered law school, David Casarrubias served as a panel judge for the United Spirit Association. That early role put him in a position of responsibility and introduced him to the procedures of review and decision-making. He went on to earn a J.D. from the University of California College of the Law, San Francisco in 2018 after completing his undergraduate studies at California State University, Long Beach in 2014.
His path through the legal world has been steady and varied. In 2014 he worked as an executive assistant at a small law office, which gave him a close-up view of legal practice management. He spent the summer of 2016 as a judicial extern with the U.S. Department of Labor. The following year he returned to Hanson Bridgett LLP as a summer associate, and by 2018 he joined the firm as a lawyer. In 2022 he took on a classroom role as an adjunct professor at University of California, Hastings College of the Law, teaching students while maintaining his practice.
Casarrubias has built a practice that reaches into federal and appellate courts. He holds admissions that include the U.S. Supreme Court, the Ninth and Tenth Circuit Courts of Appeal, the U.S. District Courts for the Northern and Eastern Districts of California, and the State Bar of California. Those credentials inform the kinds of matters he handles and the settings where he appears.
He is active in bar and affinity organizations. He currently serves as Chair of the Young Lawyers Division of the Hispanic National Bar Association. He is a member of the Leadership Council on Legal Diversity and participates on the Executive Committee of the Bar Association of San Francisco’s Appellate Law Section. He is also involved with Bay Area Lawyers for Individual Freedom, the Barristers Club of the Bar Association of San Francisco, the San Francisco La Raza Lawyers Association, and the National LGBT Bar Association. Those memberships have shaped his professional network and provided regular outlets for continuing legal education and committee work.
Colleagues note his willingness to take on appellate briefing and federal-court filings, and his classroom work reflects a comfort with explaining legal principles to others. He has balanced practice, teaching and committee responsibilities while remaining at Hanson Bridgett LLP. He is a lawyer at Hanson Bridgett LLP, where he handles appellate matters and work in federal courts.
