About William

Bill Berlin is a shareholder in the Washington, D.C., office and heads the firm's antitrust practice group. Bill concentrates his practice on counseling and defending hospitals, health systems, physicians and other health care providers in federal and state antitrust enforcement agency investigations, as well as litigation, involving mergers and acquisitions, joint ventures and provider networks, exclusionary conduct by dominant firms and contracting provisions between hospitals, physicians and health plans. His litigation and government investigations frequently involve managing difficult procedural issues, including large-scale electronic discovery. Bill also serves as a monitor, arbitrator and mediator in antitrust disputes between health care entities. Prior to joining Hall Render, he was in private practice and served as a senior trial attorney with the Antitrust Division's Health Care Task Force of the U.S. Department of Justice where he led investigations and litigation of both merger and non-merger civil antitrust cases. Most recently, Bill was appointed Monitoring Trustee by the Department of Justice and approved by the court to oversee two multi-billion dollar merger divestitures.
