Seven lawyers, including four corporate and litigation partners, have left New York’s Robinson Brog Leinwand Greene Genovese & Gluck to start a regulatory compliance group at Sullivan & Worcester.

Partners David Danovitch, Peter Ginsberg, Scott Miller and John Riley and associates Nicholas Chionchio, Michael DeDonato and Nakia Elliott joined Sullivan’s New York office, the firm said on May 22, growing its expertise in transactions, financing and securities compliance, as well as litigation and white-collar matters. The 170-lawyer Boston-based firm now has about 40 lawyers in New York.
