Biography:

Gregg Mashberg is the immediate past chair of Proskauer Rose’s Litigation and Dispute Resolution Department. He has a broad-based practice and experience before numerous judicial and administrative forums.

A 1977 graduate of N.Y. U. Law School, he was elected to the Law Review at SUNY Buffalo Law School where he completed his first year of study. Gregg spent five years in the New York City Corporation Counsel's Office, becoming an Assistant Chief of the General Litigation Division. In that position, Gregg was lead counsel for the City in major institutional change class actions. He also represented the City in litigation concerning significant public policy disputes. As an Assistant Corporation Counsel, Gregg won the Award for Excellence of the Municipal Affairs Committee of the Association of the Bar of the City of New York.

Since entering private practice, Gregg has maintained his interest in public law, most recently serving as lead counsel to the Metropolitan Transportation Authority in successfully defending against challenges to the MTA’s 2003 decision to raise fares and tolls.

Gregg also concentrates in securities litigation, defending public companies and their directors and officers in class actions, SEC investigations and enforcement actions. Gregg also has broad experience in defending directors and officers in shareholder derivative actions and direct breach of fiduciary duty suits under state law.

As part of his securities litigation practice, Gregg is outside litigation counsel for The Depository Trust & Clearing Corporation and its subsidiaries, the nation's principal securities settlement and depository institutions. Gregg has litigated in trial and appellate courts around the country, successfully defending against claims challenging the securities clearing and settlement system.

Gregg also has substantial litigation experience involving core aspects of Proskauer’s litigation practice, including antitrust, bankruptcy, entertainment, sports, First Amendment, trade secrets and general commercial disputes. He recently won summary judgment on behalf of a major British company, dismissing a complaint seeking $100 million in damages. Gregg is an experienced courtroom lawyer; for example, he won a $3 million federal jury verdict in a stockholders’ derivative action in a case involving the closing of a Wall Street brokerage house.

Gregg is a Trustee of the Washington Institute for Near East Policy, and a Member of the Executive Committee of the New York Regional Board and a National Commissioner of the Anti-Defamation League. He is the immediate past Co-chair of the Lawyers Division of the ADL’s New York region and currently Co-chair of the International Affairs Division of the ADL’s New York region.
