Leigh Oliver, a partner at Hogan Lovells in Washington, D.C., helps companies step through their most difficult antitrust issues, from strategic transactions to government investigations. She represents clients before both state and federal antitrust enforcers on matters such as domestic and multijurisdictional mergers, joint ventures, and competitor collaborations.

In 2016, she was named an M&A Antitrust Trailblazer by the National Law Journal.

Previously, Leigh was also a key member of the winning defense team in LabCorp v. FTC, which was named "Litigation of the Year" at the 2011 Global Competition Review Awards. Leigh is known for her tireless work ethic, which helps her build important relationships with witnesses and clients to gain an in-depth knowledge of markets and competitive dynamics that is essential to her winning advocacy.
