Jason Alperstein

Jason Alperstein focuses his practice exclusively on the litigation of complex class actions, including cases involving automotive safety defects, mass torts, and data breaches. As a tireless advocate for consumers throughout his career, Jason has a long track record of success in helping implement significant business reforms, recovering billions of dollars for those injured by fraudulent schemes and deceptive and unfair business practices.

Jason was an integral member of the team that litigated In re Volkswagen “Clean Diesel” Marketing, Sales Practices, & Prods. Liab. Litig., No. 15-md- 2672 (N.D. Cal.), prosecuting claims on behalf of almost 600,000 consumers who were duped into purchasing and leasing Volkswagen, Audi, and Porsche vehicles that were fraudulently and falsely marketed as environmentally friendly. Jason was involved in almost all aspects of the litigation, which resulted in a series of settlements that totaled well over $17 billion, the largest consumer automotive settlement in history.

On the heels of the landmark “Clean Diesel” settlement, Jason helped obtain an $840 million global settlement in In re Chrysler-Dodge-Jeep EcoDiesel Marketing, Sales Practices and Prods. Liab. Litig., No. 3:17-md-02777-EMC (N.D. Cal.), which involved similar misconduct. Jason was also involved in some of the nation’s most significant consumer privacy cases, including In re Yahoo! Inc. Customer Data Security Breach Litig., No. 5:16-md-02752-LHK (N.D. Cal.), which resulted in a $117.50 million recovery after the largest data breach in history.

Prior to these landmark recoveries, Jason served on lead and co-lead litigation teams in nationwide and statewide class action lawsuits against dozens of the nation’s largest banking institutions in connection with the unlawful assessment of checking account overdraft fees. His efforts resulted in over $250 million in settlements for his clients and significant changes in how banks charge overdraft fees to their customers. Most recently, Jason was appointed co-lead counsel in several class actions involving insurers’ failure to pay the “actual cash value” on first-party total loss vehicle claims, including in Paris, et al. v. Progressive American Ins. Co., et al., No. 19-cv-21761 (S.D. Fla.), where he obtained a $38 million settlement on behalf of Florida insureds.

Jason has repeatedly been recognized by several leading industry organizations for his success in his class action practice. Benchmark Litigation has named him to its 40 & Under Hot List four years in a row (2018-2021), Law360 recognized him as a Consumer Protection Rising Star in 2017, and from 2014-2019 he was selected as a Florida Super Lawyer “Rising Star” in the Class Action & Mass Tort category. Jason is also a frequent speaker on issues pertaining to class action practice and procedure.

A graduate of Brown University, Jason earned his law degree, cum laude, from the University of Miami School of Law, where he was a member of the Business Law Review. Jason also obtained a Master of Business Administration in Finance from the University of Miami School of Business, where he was a Graduate Assistant Scholar.

Before practicing law, Jason served as an intern for United States Senator Bob Graham in Washington, D.C., and as an intern for Wolf Blitzer Reports in CNN’s Washington, D.C. bureau.
