Patricia (Pat) A. Brannan

General Counsel
Washington, D.C.

Patricia (Pat) A. Brannan

Pat Brannan is general counsel of Hogan Lovells US LLP, the lead lawyer representing the firm in the Americas. She manages litigation, claims, legal compliance, ethics, and risk management issues relating to the law practice of Hogan Lovells. The general counsel role is the culmination of her 35-year career.

Pat has dealt comprehensively with the complex ethical challenges that face most lawyers throughout their careers. For decades, a central focus of her practice has been compliance with professional ethical and conflict of interest requirements. Her background as a practice leader (Education Practice Group, 1995-2004 and Pro Bono Practice, 2004-2011) provided Pat with the experience needed to ground her compliance advice in the realities of our complex global law practice. She served as co-chair of the firm's Legal Ethics Committee from 2002-2011.

Before becoming HLUS general counsel in 2012, Pat represented clients in arbitrations and in bench trials, jury trials, and appeals in federal and state courts throughout the United States. Her appellate practice has featured arguments before the U.S. Supreme Court and most of the federal courts of appeal. Pat was a former Chair of the Board on Professional Responsibility for the District of Columbia. She also taught professional responsibility at the George Washington University School of Law.

Pat clerked for the Honorable John M. Ferren on the District of Columbia Court of Appeals for one year before joining Hogan & Hartson (now Hogan Lovells), as an associate in 1980.
