Crowell & Moring has named Edwin Baum managing partner of the firm’s New York office, taking the place of corporate partner Joseph Adams, who has led the New York office for four years and will continue his practice at the firm.

Baum, 54, is a commercial litigator who joined Crowell & Moring in May 2012 from Proskauer Rose. Crowell & Moring, based in Washington, D.C., has about 500 attorneys firm wide. Baum sits on the firm’s 12-member management board.

Most of Crowell’s 62 attorneys in New York are litigators. Baum said the New York office has plans to expand in securities, commercial, financial services and antitrust practices, as well in intellectual property, insurance and reinsurance. Baum said he would like the office to grow to 75 to 100 lawyers in near term but added that there is no set target. The firm is “more focused on finding the right people,” he said.

Although financial crisis litigation has waned, “we’ve seen a significant increase in M&A and securities litigation” and “steady uptick in the overall volume of litigation,” Baum said.

Baum said the firm, including the New York office, is increasingly using alternative fees. “Clients are asking for it with far greater frequency now,” including flat, blended and contingency fees, among other arrangements, he said.
