Cohn & Swartzon expands Oz Tannenbaum’s injury practice statewide

Cohn & Swartzon LLP says partner Oz Tannenbaum is broadening his personal injury practice across California, using more than a decade of insurance defense experience to pursue serious injury and wrongful death claims. The Irvine-based attorney now represents clients statewide and has helped recover millions of dollars, including one case that grew from a potential $100,000 payout to $725,000.

Why it matters: - Oz Tannenbaum brings insurance defense experience to plaintiff-side injury cases, which can help expose coverage, valuation, and litigation tactics that may affect recovery. - Cohn & Swartzon LLP is expanding a practice that serves injured Californians in serious injury and wrongful death matters across the state. - The firm says clients work directly with an attorney throughout the case, which can matter in high-stakes claims that require frequent communication and fast decisions.

What happened: - Cohn & Swartzon LLP announced the continued statewide expansion of partner Oz Tannenbaum’s personal injury practice on July 29, 2026. - Tannenbaum is based in Irvine and represents clients throughout California, including Orange County, Los Angeles County, Riverside County, San Bernardino County, San Diego County, and the Central Valley. - Tannenbaum spent more than 10 years defending insurance companies and their insureds before switching to plaintiff-side work in 2017. - He joined Cohn & Swartzon LLP in 2021 after leading the litigation department at a plaintiff’s personal injury firm for four years. - His practice covers motor vehicle collisions, commercial trucking accidents, premises liability, dog attacks, and catastrophic injury cases.

The details: - Tannenbaum says his defense background gives him firsthand knowledge of how claims are evaluated, investigated, negotiated, and litigated. - His work has recovered millions of dollars for injured clients over his career. - One case that initially appeared capped by a $100,000 insurance policy ultimately led to a $725,000 recovery after further investigation. - Tannenbaum says his approach centers on careful preparation, thorough investigation, and an understanding of defense strategy. - He said his goal is to identify every available avenue of recovery and pursue the compensation clients deserve. - Tannenbaum earned a bachelor’s degree in Finance, Real Estate, and Law from California State Polytechnic University, Pomona, and a Juris Doctor from Southwestern Law School in Los Angeles. - He participated in the Moot Court Honors Program at Southwestern Law School. - Super Lawyers has recognized Tannenbaum each year from 2022 through 2026. - He is a member of the Orange County Bar Association and the Orange County Trial Lawyers Association. - Cohn & Swartzon LLP was founded in 2008 and focuses on serious injury and wrongful death cases. - The firm’s practice areas also include automobile and trucking accidents, catastrophic injuries, traumatic brain injuries, spinal cord injuries, dog bites, motorcycle and bicycle accidents, pedestrian accidents, rideshare collisions, premises liability, and mesothelioma and asbestos exposure. - The firm offers free consultations, works on a contingency fee basis, and provides services in English and Spanish.

Between the lines: - Tannenbaum’s switch from defense to plaintiff work suggests the firm is leaning on insider knowledge of how insurers assess risk and pressure claims. - The $100,000-to-$725,000 example illustrates how additional investigation can materially change the value of a case when coverage appears limited. - The statewide footprint points to a strategy aimed at serving clients beyond Orange County while keeping the practice anchored in Irvine.
