Bill Efron, former Director of the Northeast Region of the Federal Trade Commission, is a member of the firm’s Antitrust/Competition practice. With more than two decades of experience, Bill focuses on antitrust and consumer protection with an emphasis on merger reviews, government investigations, and litigation. His practice encompasses anticompetitive conduct matters, government enforcement actions, private litigation, and counseling.
Bill has deep senior government experience in both antitrust and consumer protection. Prior to joining Arnold & Porter, he served as Director of the FTC’s Northeast Region for over 12 years. In that role, he was responsible for enforcing federal antitrust laws through merger and anticompetitive conduct investigations and litigation. On behalf of the FTC’s Bureau of Competition, Bill led and supervised antitrust matters across an array of industries, including healthcare, digital platforms, retail, medical devices, radiopharmaceuticals, and industrial products.
During his tenure at the FTC, Bill handled high-profile, cutting-edge, and highly complex matters. His experience includes serving as lead trial and appellate counsel in the FTC’s successful challenge to the proposed $2.4 billion merger of Penn State Hershey Medical Center and PinnacleHealth System. Bill argued the FTC’s appeal before the Third Circuit Court of Appeals, which issued a precedential opinion related to the analysis of hospital mergers. Bill and the litigation team received the FTC’s Janet D. Steiger Award for their work on the case. While his industry experience is broad, Bill has particular strength in healthcare and possesses significant experience with respect to digital platforms.
As Director of the FTC’s Northeast Region, Bill was also responsible for the investigation and litigation of consumer protection matters. On behalf of the FTC’s Bureau of Consumer Protection, he oversaw complex cases involving a range of alleged unfair, deceptive, and fraudulent practices, including deceptive internet marketing, unauthorized billing, misleading earnings claims, false advertising online, and credit card laundering.
Prior to joining the FTC, Bill practiced as an antitrust and commercial litigator at an Am Law 100 law firm.
