BakerHostetler announced today that Ann O’Brien, most recently assistant chief of the Competition Policy & Advocacy Section and special counsel for Criminal Policy at the US Department of Justice (DOJ) Antitrust Division, has joined the firm as a partner in the firm’s Washington, DC, and Philadelphia offices.
O’Brien is the third recent notable addition to BakerHostetler’s Antitrust and Competition team, following Jeffrey Martino, former chief of the DOJ Antitrust Division’s New York office, and Marc Schildkraut, former assistant director with the Federal Trade Commission’s Bureau of Competition in Washington, D.C. O’Brien will also serve as part of the firm’s White Collar, Investigations and Securities Enforcement and Litigation team.
Over nearly two decades, O’Brien rose through the DOJ’s ranks to hold senior leadership and management positions. She served as a trial attorney, a special assistant to the civil and criminal directors of enforcement in the Office of Operations, the assistant chief of two sections, counsel to the assistant attorney general, senior counsel, and acting director of criminal enforcement.
As acting director, O’Brien was the second-highest career official running the Antitrust Division’s criminal program, where she supervised more than 120 attorneys across five offices.
“Ann brings to our nationally recognized, diverse antitrust team extraordinary senior leadership experience at all levels of the DOJ Antitrust Division, including serving as the acting director of criminal enforcement managing the division’s cartel investigations and prosecutions internationally, and she was one of the top-ranking women in the division,” said Carl W. Hittinger, BakerHostetler’s Antitrust and Competition team leader.
