More informationMore information

Clifford Chance draws considerable praise from clients, who turn to the team for its ability to ‘see across a multi-jurisdictional chessboard.’ The firm adeptly handles cross-border merger clearances, DOJ and FTC investigations, with notable expertise in facilitating approvals in healthcare and life sciences transactions. The team is led by Timothy Cornell, a prolific merger counsel noted for his expertise in multijurisdictional clearance processes and investigations, and Sharis Pozen, who has deep agency experience and specializes in merger litigation, both in the US and against global enforcement bodies. Brian Concklin handles DOJ and FTC approvals for deals, as well as advising on transactions requiring multijurisdictional approvals, while Robert Houck represents clients in complex commercial litigation. The team’s litigation capabilities have been bolstered by the 2023 arrival of William Lavery and Joseph Ostoyich from Baker Botts L.L.P., as well as the 2024 arrival of counsel Lauren Rackow in New York from Cahill Gordon & Reindel LLP. Attorneys mentioned are based in Washington DC unless otherwise stated.
