Zachary Arbitman

Zac Arbitman has helped recover over a quarter of $1 billion 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.

For his work, Zac 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. The First Judicial District of Pennsylvania also recognized him in 2013 and 2015 on its annual Pro Bono Roll of Honor.

Zac joined Feldman Shepherd in 2021, after establishing a stellar reputation as a skilled and zealous advocate.  He began his career at a well-known Am Law 100 firm, where he gained valuable insights into strategies used by large corporations defending bet-the-company litigation.  This experience on the other side of the “v” has greatly benefitted Zac in his current practice representing plaintiffs in their most critical matters.

Zac leads the whistleblower representation and class action practices at Feldman Shepherd.  He represents whistleblowers in claims regarding healthcare and government contracts fraud; securities and commodities fraud; tax fraud; auto safety; and money laundering, sanctions evasion, and corruption.  Zac’s class action work is equally diverse and centers on important consumer protection cases, with a particular focus on matters concerning dangerous products, false advertising, unfair business practices, cybersecurity, and data privacy.  His catastrophic personal injury and wrongful death practice is just as varied—with experience in medical malpractice, defective products, motor vehicle accidents, workplace injuries, unsafe premises, and civil rights cases. 

The common threads in each case that Zac handles are his dedication to clients, attention to detail, and focus on results.  Whether through trial, appeal, or settlement, he and his firm invest the resources to take on the toughest opponents in difficult and sometimes lengthy litigation.  Zac’s passion for leveling the playing field and obtaining compensation for the individuals and families he represents is what fuels his grit and determination.

Outside the office, Zac remains active in his community. He is a member of the Board of Directors for the Public Interest Law Center and Chair of its Nominations Committee. Zac is also Vice Chair of the Philadelphia Bar Association’s Federal Courts Committee and part of the Judicial Education Committee for Taxpayers Against Fraud, a nonprofit public interest organization dedicated to combating fraud against the Government through whistleblower law. Previously, Zac served on the Member Education Committee of TAF and 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 the George Washington University Law School, where he was selected to serve as a Research Assistant for now-Provost 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 two daughters. In his free time, he enjoys relaxing with his family, playing basketball and golf, and reading.
