Jonas has secured significant victories for clients, including:

- Federal trial win representing minority shareholders in a in breach of fiduciary duty & corporate waste case involving a $250 million company

- Represented multiple celebrities and fashion models for misappropriation of likeness and Lanham Act violations in connection with the unauthorized use of their image in advertising.

- Obtained a favorable False Claims Act ruling on behalf of a state attorney general and successfully defended all appeals, including obtaining denial of a writ of certiorari to the United States Supreme Court.

- Represented borrowers in litigation resulting in nationwide class settlement against financial institution for breach of contract in auto leases.

Jonas earned his J.D. from Temple University, James E. Beasley School of Law, where he was an editor of the Temple Political and Civil Rights Law Review. Following law school, he clerked for the Honorable Carol E. Higbee at the Superior Court of New Jersey. Before joining UMK, he practiced at national litigation firms in San Francisco and Los Angeles.

Admitted to the most courts of any UMK attorney, he brings both top-tier credentials and a driven approach to achieving results for clients. We’re proud to spotlight Jonas and everything he continues to accomplish at UMK Law.
