Bona Law announced that antitrust lawyer Jon Cieslak is leaving Cooley to join Bona Law as a partner March 13, 2020.
Cieslak brings with him nearly a decade of antitrust litigation and white-collar criminal defense experience, which will further enhance the firm’s full-service antitrust practice.
“Jon Cieslak has talent and experience that will reinforce the firm’s existing antitrust and competition capabilities,” said Jarod Bona, CEO of Bona Law, “but he will also enhance our ability to defend corporate clients and their executives in investigations and actions by the US Department of Justice Antitrust Division and other law enforcement agencies.”
His addition comes at a time when the government is ramping up antitrust enforcement efforts, which often means parallel criminal and civil proceedings for antitrust defendants.
Cieslak earned his undergraduate degree from Princeton University and his juris doctor from the University of California – Los Angeles School of Law. After law school, he clerked for US District Judge Jeffrey Miller in the Southern District of California before joining Cooley.
