Zac Arbitman has helped recover over $250 million in whistleblower, class action, and catastrophic personal injury cases. He has been handling high-stakes matters for more than a decade and leverages his experience, in combination with an ability to innovate, to best represent his clients. With this approach, Zac has achieved many significant results in trials, appeals, and alternative dispute resolution forums in Pennsylvania, New Jersey, and other courts throughout the United States.
Zac joined Feldman Shepherd in late 2021, after establishing a well-earned reputation as a skilled and zealous advocate. He has been named a Pennsylvania Super Lawyers Rising Star by Pennsylvania Super Lawyers every year since 2014 and a Lawyer on the Fast Track by the Legal Intelligencer in 2022. In addition, the First Judicial District of Pennsylvania also recognized Zac in 2013 and 2015 on its annual Pro Bono Roll of Honor.
At the firm, Zac leads the whistleblower representation practice and brings claims on behalf of whistleblowers under state and federal False Claims Acts, various state whistleblower statutes, and the SEC, CFTC, IRS, FinCEN, and NHTSA whistleblower programs. Over his career, he has helped whistleblower clients achieve many significant recoveries, including in cases where the government has declined to intervene. For example, Zac was part of the team at a previous firm that ultimately achieved a $40 million settlement in two declined False Claims Act cases alleging that Bayer violated anti-fraud laws in selling and promoting three drugs: Trasylol, Avelox and Baycol. U.S. ex rel. Simpson v. Bayer Corp., et al. 05-cv-3895 (D.N.J.); U.S. ex rel. Simpson v. Bayer Corp, et al. Civ. No. 08-cv-5758 (D. Minn.).
Zac’s class action experience is equally diverse and centers on important consumer protection cases—namely, product liability, false advertising, and antitrust matters. Prior to joining Feldman Shepherd, Mr. Arbitman prosecuted numerous class actions that have resulted in significant recoveries, including: In re: Liquid Aluminum Sulfate Antitrust Litigation, No. 16-md-02687 (D.N.J.) (over $90 million in settlements in antitrust class action alleging defendants unlawfully allocated customers and markets and fixed the price of liquid aluminum sulfate); In re: The Bank Of New York Mellon ADR FX Litigation, 1:16-cv-00212 (S.D.N.Y.) ($72.5 million settlement in class action alleging BNY Mellon overcharged American depositary receipt holders for the conversion of foreign currency dividends to U.S. dollars); In Re Zinc Antitrust Litigation, Case No. 14 Civ.3728 (PAE) (S.D.N.Y) ($9.85 million recovery in an antitrust class action alleging monopolization and attempted monopolization conduct resulting in inflated market pricing for Special High Grade Zinc).
Zac also handles a wide array of catastrophic personal injury cases involving medical malpractice, defective products, motor vehicle accidents, workplace injuries, unsafe premises, and civil rights violations. In the last five years, while at both Feldman Shepherd and his prior firm, he has helped make almost $35 million in recoveries—many of which are confidential—for his personal injury clients.
Outside the office, Zac remains active in his community. He is an elected member of the Board of Directors of the Public Interest Law Center and is Co-Chair of its Nominations Committee. He is also involved in the Taxpayers Against Fraud Education Fund, a nonprofit public interest organization dedicated to combating fraud against the Government, and is a member of its Conference and Member Education Committee. Previously, Zac served on the Executive Committee of Justice Rising Advocates for Community Legal Services of Philadelphia.
Zac earned his B.A. magna cum laude from Haverford College, where he was inducted into The Phi Beta Kappa Society. He earned his J.D. from George Washington University Law School, where he was selected to serve as a Research Assistant for Professor Christopher A. Bracey for a book on race, racism, and the law. Zac remains active in the alumni networks of GW Law, Haverford College, and the Episcopal Academy, where he attended high school.
Born and raised in Philadelphia and its surrounding suburbs, Zac lives in the area with his wife and daughter. In his free time, he enjoys relaxing with his family, playing basketball and golf, and reading.
