During Creighton's time at the DOJ, the Antitrust Division undertook an unprecedented volume of high-profile civil and criminal matters.

Creighton began his career as a Trial Attorney in the Litigation III and Transportation, Energy, and Agriculture sections of the Antitrust Division, working on a number of notable merger and civil non-merger investigations and cases.

Creighton is consistently recognized globally for his market-leading antitrust practice with respect to high-stakes transactions, investigations, and compliance and counseling work. For example, clients have noted that Creighton "shines above the rest' due to his first-rate cartel and merger control-related practice.'"

Creighton is currently Co-Chair of the American Bar Association Antitrust Law Section's Young Lawyers Task Force.
