WILLIAM WELD, former governor of Massachusetts, is joining both Mintz Levin Cohn Ferris Glovsky and Popeo and the Boston-based firm’s government consulting arm, according to sibling publication The National Law Journal.

Weld—who most recently split his time as of counsel in the New York and Washington, D.C., offices of McDermott Will & Emery—will be a partner in Mintz Levin’s Boston office and a principal at affiliate ML Strategies LLC starting October 22. Weld served as governor of Massachusetts from 1991 to 1997 before joining McDermott, where he headed that firm’s New York office for a time and advised on litigation, legislative investigations, and government strategy matters. He left McDermott from 2001 to 2005 for a private equity gig with what is now known as Leeds Equity Partners. (He also made an unsuccessful bid to become governor of New York in 2006.)
