Health care companies can expect more antitrust enforcement activity in the next few years, and law firms will be increasingly called on to represent them, according to Andre Geverola, a former Justice Department attorney who moved to Arnold & Porter Kaye Scholer on Monday.

Geverola was the director of criminal litigation in the Justice Department’s antitrust division until June 4. He has joined Arnold & Porter’s antitrust and competition practice group as a partner.
