From Defense to Advocacy: Leveraging
Litigation Experience to Fight for the Injured
Oz was admitted to the California Bar in 2005 and has been practicing law for nearly two decades. Before joining Cohn & Swartzon in 2021, he spent almost a decade as a litigator at Murtaugh Meyer Nelson & Treglia LLP (now Murtaugh Treglia Stern & Deily LLP). During this time, he gained extensive experience in all phases of litigation, honing his skills in case strategy, negotiation, motion practice, and trial advocacy.
While defending individuals and businesses in personal injury and wrongful death cases, Oz developed a comprehensive understanding of how the defense side approaches litigation. This unique insight now allows him to anticipate defense strategies and build stronger, more effective cases for injury victims seeking justice.
Since transitioning to plaintiff representation at Cohn & Swartzon, Oz has leveraged his litigation background to fight for maximum compensation for his clients, helping them rebuild their lives after serious accidents.
Experience That Produces Results
Oz speaks with every single client at various stages of litigation and has always provided one-on-one attention to each client’s case, regardless of the nature or extent of the injuries sustained. This personal approach to each client’s case is a challenging and rewarding experience for which he is particularly proud.
Additionally, Oz spent years defending the interests of insurance companies, where he gained first-hand knowledge of how they evaluate cases to minimize paying full and fair compensation to injured persons and/or their families. He puts his knowledge and experience of the opposition’s tactics to use every day in meticulous preparation and vigorous advocacy for his clients.
