The firm’s founder, Robert S. Sinsheimer, first opened his firm doors in 1990. Attorney Sinsheimer and his firm are known in Boston for the very highest degree of personal service. Rob brings unparalleled perseverance to his cases – a quality which moved a local newspaper to describe him (for better or worse) as a “pitbull.” Rob’s truly unique background allows him to bring these qualities to an unusually broad array of litigation issues and strategies.
Peter R. Cruice joined the firm as an associate in 2019. He has been a member of the Massachusetts Bar and the United States District Court of Massachusetts since 2019. While in law school, Peter spent his first-year summer and the fall of his second-year working for the Suffolk County District Attorney as an intern. During his second-year summer, Peter was an SJC Rule 3:03 student prosecutor. Peter has also clerked at multiple civil litigation firms.
