Jason H. Alperstein

Partner

Jason Alperstein is a partner at Kopelowitz Ostrow P.A. (“KO”) and his practice focuses 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 developed a track record of success in helping to implement significant business reforms and recover billions of dollars on behalf of those injured by fraudulent schemes and deceptive and unfair business practices.

Jason began his career as a class action litigator with KO in 2009 and rejoined the firm in 2021 after having the privilege of representing consumers around the country in some of the most important and unprecedented class actions.  As a partner with Robbins Geller Rudman & Dowd LLP, 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 marketed as environmentally friendly.  In reality, those vehicles had been installed with “defeat devices” that concealed the vehicles’ true emission levels, which were up to 40 times the legal limit permitted by the EPA.  Working closely with Lead Counsel and the Plaintiffs’ Steering Committee (“PSC”), Jason was involved in almost all aspects of the litigation, including at the appellate level.  The PSC and government agencies ultimately reached a series of settlements on behalf of purchasers, lessees and dealers 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.), for similar “defeat devices” installed in Jeep and Dodge diesel trucks and SUVs that were marketed as environmentally friendly “EcoDiesel” vehicles.  Jason was also involved in some of the nation’s most significant privacy cases, including In re Yahoo! Inc. Customer Data Security Breach Litig., No. 5:16-md-02752-LHK (N.D. Cal.), where he assisted Lead Counsel in obtaining a $117.50 million recovery in the largest data breach in history.

Prior to these landmark recoveries, and as a partner with KO, Jason served on lead and co-lead litigation teams in nationwide and statewide class action lawsuits against dozens of the 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 the way banks charge overdraft fees to their customers.  In addition, Jason led consumer class actions against product manufacturers for false and deceptive labeling, and some of the world’s largest clothing retailers for their use of false and deceptive comparative pricing in their outlet stores.  Before shifting his focus to class action litigation, Jason successfully represented institutional investors in securities fraud and derivative actions seeking damages related to the origination and servicing of residential mortgage-backed securities.  He also gained substantial experience representing both plaintiffs and defendants in business litigation disputes involving trademark infringement, theft of trade secrets, fraudulent and negligent misrepresentation, breach of fiduciary duty, breach of contract, tortious interference, and commercial real estate litigation.

Jason has been recognized by several leading industry organizations for the success he has achieved in the class action practice area.  For the past three years, Benchmark Litigation has named him to its 40 & Under Hot List (previously known as the Under 40 Hot List) for being “ambitious and accomplished lawyers [who] frequently handle major cases – some of which are high-stakes or precedent-setting.”  The publication honors “the best and brightest law firm partners who stand out in their practices throughout the US and in Canada.”  In 2017, Jason was recognized by Law360 as a Consumer Protection Rising Star, and from 2014-2019 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, having presented for The Florida Bar, the Florida Alliance of Paralegal Associations, and the Stanford Plaintiffs’ Lawyers Association.

Jason earned a dual Bachelor of Arts degree in Political Science and Sociology, with honors, from Brown University.  While at Brown, he was a sprinter on the Varsity Track & Field team, studied at the University of Melbourne in Australia, and served as an intern for Judge Gilbert V. Indeglia of the Superior Court of Rhode Island.  Jason received a Juris Doctor degree, cum laude, from the University of Miami School of Law, where he was a member of the Business Law Review, and a Masters of Business Administration in Finance from the University of Miami School of Business, where he was a Graduate Assistant Scholar.

Jason is a native of South Florida and is the past Miami-Dade Area Chair of the Brown Alumni Schools Committee. He also is a founding member of the American Heart Association’s PULSE, has been inducted into the Leadership Broward Foundation, and is a graduate of the National Outdoor Leadership School (NOLS).  Prior to 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 the Washington, D.C. bureau of CNN.
