Government Investigations + Enforcement Matters
For more than 25 years, Pat has helped clients facing civil and white-collar criminal investigations and prosecutions.

Pat frequently works closely with HWG’s telecoms team to help communications companies respond to federal regulatory investigations, including several investigations involving the FCC’s universal-service subsidy program.

Legal Ethics
Pat has advised corporate legal departments and individual lawyers on compliance with legal ethics and professional responsibility issues in Virginia and the District of Columbia and represented clients in investigations of alleged violations. In addition to counseling clients on legal ethics issues, Pat has served as General Counsel of HWG for almost 20 years, helping the firm proactively address potential ethics issues with a thoughtful, practical counsel.

Civil Litigation
Pat has secured major victories for clients in complex civil litigation, including:

• winning the vacatur of a judgment and dismissal of a case against a nation state on grounds of sovereign immunity;
