Mr. Cassidy focuses on legal issues raised by cross-border business transactions, including antidumping and countervailing duty proceedings, economic sanctions, export controls and customs issues.

Mr. Cassidy served as General Counsel of the Office of the US Trade Representative from 1979-1981 and International Trade Counsel to the US Senate Committee on Finance from 1975-1979.
