Marc Siegel worked for 30 years at the Antitrust Division of the U.S. Department of Justice in senior leadership positions involving criminal cartel enforcement and policy development. For almost six years as the director of Criminal Enforcement, he was responsible for managing the Division's cartel investigations and prosecutions nationwide. In that role, he reviewed, for AAG (assistant attorney general) approval, staff recommendations to grant corporate leniency, enter into corporate and individual plea agreements, and indict targets of cartel investigations. Also, as chief of two of the Division's busiest criminal offices (San Francisco and New York), Marc supervised all aspects of several high-profile international and domestic cartel investigations, including municipal bonds, auto parts, Northern California real estate foreclosure auctions, capacitors, and packaged seafood (tuna).
As a trial attorney in the Division's San Francisco office, Marc worked closely with teams of FBI agents and coordinated investigative efforts with foreign enforcers conducting parallel investigations in successfully prosecuting international cartel matters in the commodity chemicals market. He negotiated many corporate and individual plea agreements as well as corporate leniency agreements. Marc also trained hundreds of FBI and other federal agents in detecting anticompetitive conduct that violated the Sherman Antitrust Act. He earned awards of distinction from four Assistant Attorneys General.
Marc is a member of the Antitrust Section of the American Bar Association. He currently teaches courses in antitrust law and international price-fixing conduct at UC Hastings College of the Law.
