Arnold & Porter partners Debbie Feinstein and Sonia Pfaffenroth were recognized by Global Competition Review’s 2021 “Women in Antitrust” report.

Feinstein, who heads the firm’s Global Antitrust group, brings a wealth of experience to her practice in advising clients on a range of antitrust challenges before US antitrust authorities. She previously served as Director of the Bureau of Competition at the US Federal Trade Commission, where she was responsible for supervising the investigation and enforcement of the US antitrust laws against anticompetitive mergers and conduct.

Pfaffenroth focuses her practice on helping clients address complex antitrust issues in the US and globally. She previously served as Deputy Assistant Attorney General for Civil and Criminal Operations in the Antitrust Division of the US Department of Justice (DOJ). In that role, Pfaffenroth was responsible for supervising both civil and criminal antitrust enforcement efforts, as well as the Division's work with antitrust and competition law enforcement agencies worldwide.
