After spending nearly five years as an in-house leader at Visa Inc., Michael Dashefsky, a former federal antitrust attorney who also had a stint with Big Law, has returned to private practice.

Dashefsky joined Bass, Berry & Sims earlier this week as a partner and co-chairman of the firm’s antitrust and trade practices group in Washington, D.C. He’ll represent clients on antitrust matters related to mergers and acquisitions, nonmerger investigations, joint ventures and other strategic transactions.

Dashefsky stated in an email Thursday that he was “excited to join Bass, Berry & Sims and look forward to helping the firm expand its antitrust practice.”

“I look forward to sharing my knowledge and background from both my government and in-house roles to help clients with various competition issues related to transactions, investigations and litigation,” he added.

The firm noted in a news release that Dashefsky’s hiring is part of an effort to build the firm’s antitrust and trade practices group in Washington.

The office’s managing partner, John Kelly, said Dashefsky “adds significant experience and depth to the firm’s antitrust practice with more than two decades handling antitrust matters and a truly unique perspective from his background of litigating cases in federal enforcement, in-house and outside counsel roles.”

Dashefsky left Visa in November 2017 after having served as the company’s vice president and associate general counsel for global litigation and competition in Washington, D.C. He oversaw global antitrust litigation, regulatory inquiries and investigations involving various domestic and international government agencies, including the U.S. Department of Justice, Federal Trade Commission and European Commission.

Before he joined Visa and the in-house world in 2013, Dashefsky spent a decade as a trial attorney for the Justice Department’s Antitrust Division. Earlier in his career, after he graduated from Georgetown University Law Center, he went to work as an attorney in the FTC’s Bureau of Competition, where he focused on high-profile mergers and acquisitions.

Between his time with the FTC and DOJ, Dashefsky worked as an associate at Morrison & Foerster and the now-defunct Howrey law firm, according to his LinkedIn profile. He specialized in antitrust matters at both firms.
