Jonas P. Mann is an associate with the Class Action Group in Baron & Budd’s Los Angeles office, representing clients in automotive defect, banking fraud, and other complex class actions. He discovered early on that representing people in class actions is especially rewarding because it helps to level the playing field for consumers, who typically would not be able to obtain justice individually. Mr. Mann has spent the majority of his legal career helping consumers who have suffered as a result of wrongful business practices.

Prior to joining Baron & Budd, Mr. Mann worked at a plaintiff’s firm in San Francisco where he represented clients in a number of consumer fraud, employment, and data privacy class actions as well as pharmaceutical mass torts. He has successfully litigated numerous class action cases involving defective home building materials, including shingles, siding, windows, and decking. Additionally, Mr. Mann has litigated consumer fraud cases against some of the biggest names in Silicon Valley and a false labeling case against one of the country’s largest food companies.

Mr. Mann is a West Coast transplant; he was born and raised in Pennsylvania. He earned his J.D. from Temple University’s James E. Beasley School of Law in Philadelphia where he was an editor of the Temple Political and Civil Rights Law Review and a Beasley Scholar. During law school Mr. Mann participated in the school’s death penalty litigation clinical program and served as a research assistant. He graduated from law school in 2007 and was admitted to the bars of Pennsylvania and New Jersey that year. Following a clerkship at the Superior Court of New Jersey in Atlantic City, he moved to San Francisco and was admitted to the California bar.

Before entering law school, Mr. Mann earned his B.A. in International Affairs cum laude and with Departmental Honors from the George Washington University in Washington, D.C. When not at work, Mr. Mann enjoys movies and traveling.
