Paul Kaplan is a Partner in the New York office of GRSM and Co-Chair of the Antitrust Practice Group.

Paul focuses his practice on corporate and commercial litigation, including business litigation and dispute resolution, antitrust litigation and counseling, class action defense, and white collar defense and civil and criminal investigations. He represents domestic and foreign financial institutions and corporations and their directors and officers in federal and state litigation and regulatory matters. He counsels corporations on the antitrust ramifications of business transactions with a view to avoiding or minimizing exposure to antitrust claims in litigation and represents financial institutions and corporations facing regulatory or court enforcement actions.  He has represented corporations and senior executives in federal and state government investigations, involving both criminal and civil matters.

Paul has practiced law for more than 35 years with major law firms and corporations in the United States and Europe.  He began his legal career in London, England where he was an associate with an Anglo-American law firm.  Following a clerkship in Boston with the late Honorable R. Ammi Cutter, a justice of the Massachusetts Supreme Judicial Court and Appeals Court, Paul joined the legal department of AT&T in New York, then involved in a complex business reorganization and divestiture, pursuant to a federal court antitrust divestiture decree.  He also held the title of vice president at Citibank, NA (Citigroup) in the General Counsel’s office and at J.P. Morgan Chase (Chemical Bank), where he was group counsel in the bank’s Middle Market/Financial Services group.

Paul has been an Adjunct Professor of Law at Fordham Law School, where he taught an advanced antitrust course for 20 years.  He has been a guest lecturer at Hebrew University of Jerusalem, Faculty of Law, Boston University School of Law and Northeastern University School of Law.

He has organized, on behalf of the government of Israel, a financial services delegation to Israel led by the late Honorable Jack Kemp (former U.S. Representative from New York, Secretary of Housing and Urban Development and Republican Party nominee for Vice President in 1996).
