Mr. Conner brings a unique skillset and knowledge base to his clients. He draws on his nearly two decades of experience, having worked at both the FTC and the Antitrust Division of the US Department of Justice (DOJ) and in private practice, to develop innovative legal approaches to address complex antitrust issues.

During his tenure, the FTC issued the Vertical Merger Guidelines in conjunction with the DOJ, and initiated a proposed rulemaking and reexamination of the Hart-Scott-Rodino Act (HSR) rules. As Deputy Director, he coordinated the creation of the Bureau’s Technology Enforcement Division. During his tenure as Director, the Bureau of Competition ranked 3rd out of 411 agency components in the annual Best Places to Work in the Federal Government.

Mr. Conner began his career as a Trial Attorney in the Antitrust Division of the DOJ, which he joined through the Attorney General’s Honors Program. He also served as a Special Assistant US Attorney for the Eastern District of Virginia, where he first-chaired trials in federal court.
