Sills Cummis & Gross has added a co-chair to its employment law practice group and brought on a former federal prosecutor with leadership experience at the U.S. Attorney’s Office, in a pair of recent partner lateral hires.

Patricia Prezioso, most recently with Porzio, Bromberg & Newman, joined Newark-based Sills Cummis as of Feb. 22. She now co-chairs the employment and labor practice with partner David Rosen.
