After serving four years as an assistant U.S. attorney in the U.S. Attorney’s Office for the District of Delaware, Mark M. Lee has returned to private practice at Schnader Harrison Segal & Lewis.

Lee’s move is a homecoming of sorts given he worked at the law firm from 2006 through 2011 until joining the U.S. Attorney’s Office. He left the firm as an associate and rejoined as a partner in the Philadelphia office Sept. 8.
