Making a concerted effort in recent years to penetrate the antitrust litigation space, DLA Piper LLP (US) runs a nationwide practice group that acts for high-profile multinational clients in a variety of antitrust matters, with notable strengths in no-poaching agreements, alleged price-fixing and monopolization conspiracies. Philadelphia-based Lesli Esposito and San Francisco-based Lisa Tenorio-Kutzkey co-head the group, which is enjoying a trend of rapid expansion. One indication of the group’s growth was the hire, in mid-2020, of John Gibson, who joined in Los Angeles from Crowell & Moring LLP. Other key contacts include John Hamill and Robby Robertson in the Chicago office, and David Bamberger in Washington DC.
