Freshfields Bruckhaus Deringer named New York litigation partner Adam Siegel as its next U.S. regional managing partner, overseeing the firm’s New York and Washington, D.C., offices.

Siegel, who is appointed for four years, succeeds New York-based corporate partner Julian Pritchard, whose term in that role ends April 30.

Siegel will oversee the two U.S. offices, which have 171 lawyers, including 122 in New York, and will serve on the firm’s management committee.

Siegel, 45, who joined Freshfields in 2009 from Covington & Burling and was previously an assistant U.S. attorney in the Southern District, focuses on white-collar criminal defense and investigations. He is co-head of the firm’s global investigations practice

Freshfields’ U.S. litigation practice began five years ago with three partners, including Siegel. It now has 12 litigation partners, most of them in New York. The firm plans to continue to add attorneys in litigation and corporate, Siegel said.

“We’ve experienced real success in our efforts to grow litigation and now we’re planning to do so in the transactional side,” including in corporate and finance, he said.

Significant clients of its New York attorneys include Citi in litigation, BG Group in arbitration, and Foster Wheeler in corporate, Freshfields said.

The firm has 28 offices in 17 countries across the U.K., Europe, Asia and Middle East and U.S. Although the last five years have been economically challenging, Siegel said, “clients have responded very well to the ability to access one firm that can help them with these very complicated problems across the world. It’s the multinational offering that I think clients have come to value.”
