Mark Grundvig
Overview
Mark Grundvig helps clients navigate complex antitrust, government enforcement, and regulatory matters, including antitrust investigations and litigation, white collar defense, corporate compliance, and congressional inquiries. He counsels companies and individuals across a wide range of industries on antitrust compliance, providing training, risk assessments, and practical guidance aligned with current enforcement priorities. He also identifies and addresses potential antitrust risks by conducting internal investigations and developing strategies to mitigate exposure across multiple jurisdictions.
Having served over 25 years at the U.S. Department of Justice (DOJ), most recently as Assistant Chief in the Washington Criminal II Section of the Antitrust Division, Mark offers clients the unique perspective and sharpened skill set of a senior government prosecutor. His former role included the oversight of investigations and prosecutions of criminal violations of federal laws relating to competition matters, such as price fixing, bid rigging, customer allocation, and fraud; supervision of investigations and litigation; guidance on courtroom strategies, compliance initiatives, and outreach efforts; and regular coordination with foreign jurisdictions and domestic agencies. His firsthand insight into how regulators assess, investigate, and resolve antitrust matters enables him to provide practical, strategic counsel to clients facing scrutiny from federal and international enforcement authorities.
Mark’s extensive experience with matters ranging from international cartel enforcement to health care and transportation antitrust matters allows him to anticipate enforcement priorities, mitigate risk, and guide clients through high-stakes disputes.
In addition to his most recent DOJ experience, Mark boasts a long, diverse track record of critical public sector work. Earlier in his career, he spent two years working on the Senate Judiciary Subcommittee on Antitrust, Competition Policy, and Consumer Rights, where he identified competition issues, drafted legislation, resolved constituent concerns, and organized hearings involving the technology, health care, media, agriculture, telecommunications, sports, and aviation industries.
