Winston Taylor‘s antitrust practice is recognized for its strength in cartel defense, criminal investigations, and complex follow-on litigation. The group is co-led by New York-based Eva Cole and Chicago-based Jim Herbison. Herbison focuses on high-stakes civil and criminal antitrust matters, including price-fixing, bid-rigging, monopolization, and government investigations, leveraging his extensive trial experience in cartel MDLs and related criminal proceedings. Cole is a leading figure in international cartel investigations and multidistrict litigation, advising global companies facing coordinated scrutiny from US and foreign regulators. Also based in New York, Jeffrey Kessler, the firm’s former global Antitrust Practice Co-Chair, brings decades of experience leading landmark antitrust trials and cross-border cartel matters. Chicago-based Michael Mayer is a key figure in major cartel trials and criminal defense, frequently partnering with Herbison on complex antitrust investigations and follow-on litigation, while partner Kevin Goldstein is increasingly visible on federal- and state-level investigations and algorithmic pricing litigation.
