Casey B. Nathan

Partner

Casey B. Nathan is a litigation partner at Sinclair Braun Kargher, where he focuses on high‑stakes business, employment, and real estate disputes throughout Southern California. His practice includes trade secret litigation on behalf of both employers and employees, bet‑the‑company partnership and ownership disputes, large commercial business disputes, FEHA and wage‑and‑hour employment matters, and complex real estate litigation.

In addition to his litigation practice, Casey regularly serves as outside general and in‑house counsel for small businesses, advising owners on employment issues, risk management, partnership and ownership disputes, and litigation strategy with an emphasis on long‑term business objectives.

Casey has extensive experience representing businesses and individuals through all phases of civil litigation, including trial and appeal. He is known for developing targeted, strategic litigation plans designed to efficiently obtain the evidence necessary to resolve complex and often protracted disputes. His approach has resulted in numerous early dismissals, favorable settlements, and successful dispositive motions in high‑exposure matters.

Prior to joining Sinclair Braun Kargher, Casey was a litigation partner at Bremer Whyte Brown & O’Meara, LLP, where he led a team of civil litigation attorneys defending clients against a wide range of high‑exposure general liability claims. His clients have included business owners, employers, insurance carriers, contractors, and professionals across multiple industries.

Casey was also a member of the litigation team that obtained a rare interlocutory, published California Court of Appeal opinion in 2022, holding as a matter of first impression that a trial court may not deny a motion to transfer venue based on witness convenience where remote testimony is available at trial.

In recognition of his work, Casey has been selected as a Southern California Super Lawyers: Rising Star for 2025 and 2026. He also serves on the board of a local nonprofit organization.

Casey lives in Los Angeles County with his wife and son. Outside of his practice, he enjoys watching sports, traveling, and spending time with his family.
