More informationMore information

Counting blue-chip companies in the tech, consumer goods, telecoms, and pharma sectors among its impressive roster of clients, the antitrust department at Gibson, Dunn & Crutcher LLP fields a deep and experienced bench with extensive experience advising on the full range of contentious antitrust issues. In San Francisco, practice co-head Rachel Brass has notable experience advising clients in high-stakes appellate litigation before the Supreme Court, as well as handling both indirect and direct purchaser class actions. Brass works alongside co-heads Cynthia Richman and Stephen Weissman, both based in Washington DC, who take point on antitrust defense work and litigated merger challenges, respectively. Also in Washington DC is Joshua Lipton, whose broad antitrust litigation practice covers both investigations and merger challenges. The Los Angeles-based Daniel Swanson has a strong track record litigating Sherman Act Section 2 monopolization and dominance cases, while Eric Stock, in New York, is a key contact for clients in the pharma, financial services, and tech industries. Rich Parker left the team in April 2023.
