Gabrielle Tenzer is a Partner at Kaplan Hecker & Fink. Gabrielle joined Kaplan Hecker & Fink from Paul, Weiss, Rifkind, Wharton & Garrison LLP, where she spent more than ten years in the Litigation Department.  Gabrielle has experience handling a wide range of civil litigation in state and federal court, including matters involving financial institutions, insurance companies, energy companies, other commercial entities, law firms, and individuals.

At Kaplan Hecker & Fink, Gabrielle maintains a broad civil litigation practice for clients as diverse as Columbia University and Uber.  Gabrielle is also working on the firm’s representation of ten plaintiffs who are suing a number of neo-Nazi and white supremacist individuals and organizations responsible for the violence that took place in Charlottesville, Virginia, in August 2017.  Filed in federal court in Virginia, the lawsuit alleges that the organizers of the August 2017 “Unite the Right” rally violated Reconstruction-Era statutes and state laws by organizing a rally intended to result in violence.  Additionally, Gabrielle is continuing her involvement in the firm’s Time’s Up work, providing victims of sexual harassment and assault with legal representation. 

During her tenure at Paul, Weiss, Gabrielle worked on multi-billion-dollar commercial cases involving complex legal issues, extensive discovery, and lengthy court proceedings.  Gabrielle was part of a trial team in a natural resource damages case in which the plaintiff sought damages of $8.9 billion, making it one of the largest environmental damages cases ever tried. After an eight-month bench trial, the case settled for $225 million.  Gabrielle also represented some of the nation’s largest financial institutions in securities litigation, shareholder derivative suits, and adversary proceedings in federal bankruptcy court.

Before becoming an attorney, Gabrielle spent almost a decade working in the federal government in Washington, D.C.  As a Legislative Assistant to then-Senator Hillary Rodham Clinton, Gabrielle helped draft and negotiate legislation on a broad array of issues, with a focus on public works, environmental protection, and environmental health—including addressing the health concerns of local residents and first responders in the wake of the 9/11 attack on the World Trade Center.  As Associate Director of Environmental Protection at the White House Council on Environmental Quality and Communications Director of the U.S. Environmental Protection Agency’s Office of Water, Gabrielle worked to build consensus among federal agencies and outside constituencies in developing and promoting national environmental policies. She also worked for several years in the Office of Congressman Frank Pallone, Jr. (D-NJ) as a legislative assistant and legislative director.

Gabrielle clerked for the Honorable Robert W. Sweet of the United States District Court for the Southern District of New York. She received her law degree from New York University School of Law, where she served as Editor-in-Chief of the NYU Journal of Legislation & Public Policy.  Gabrielle received an M.S. in Geology from the University of Michigan and a B.A. in Geology from Yale University.
