About Sebastian
Sebastian Titus earned his J.D. from the University of San Francisco School of Law. He later secured admission to practice in California. His education combined classroom training with practical clinics and internships common to USF’s curriculum, shaping the early contours of his legal approach.
Before entering private practice, Titus served as a commissioned officer in the United States Marine Corps. He spent years in uniform, taking on leadership responsibilities and the kind of decision-making that military officers face under pressure. That service gave him firsthand experience with administrative processes and the organizational dynamics of large institutions.
After his military career, Titus moved into the private sector. He worked at BioMarin Pharmaceutical, Inc., where he supervised cell culture operations. The role placed him in the middle of technical teams, manufacturing processes, and regulatory oversight. He managed day-to-day operations and coordinated with scientists and quality personnel to keep production aligned with company standards. The position exposed him to the intersecting concerns of science, compliance, and workplace procedures.
Those varied experiences inform his transition to law. Titus combines military leadership and life-sciences operations when he evaluates client problems. He approaches legal questions by parsing factual details, identifying procedural steps, and considering institutional constraints. Colleagues describe him as deliberate in the way he prepares a case file and clear when he presents options to a client.
Titus now practices from Main St. Legal. He handles matters that benefit from his background in disciplined decision-making and technical environments. His practice style tends to emphasize document review, factual reconstruction, and procedural rigor. He represents clients in California, advising on issues where operational knowledge and legal rules intersect.
In the office he keeps a steady pace. He balances litigation preparation with client counseling and draws on his prior supervisory roles when coordinating outside experts or technical witnesses. He is currently practicing at Main St. Legal and focuses on legal matters for California clients where his military and life-sciences experience is relevant.
