Ropes & Gray has added a veteran securities prosecutor to its San Francisco office.

Jonathan Schmidt, who spent nearly two decades as an assistant U.S. attorney in the Northern District of California, has joined the firm’s government enforcement group as counsel.

Ryan Murr, managing partner of Ropes & Gray’s San Francisco office, said in a statement that Schmidt’s solid reputation and his extensive experience would bolster the firm’s advisory abilities.

Schmidt also helps fill vacancies in the firm’s local white-collar practice. Last year, Michael Li-Ming Wong and Thad Davis jumped to Gibson, Dunn & Crutcher’s S.F. office.

Schmidt has tried more than 70 jury trials in his career. Before his most recent post in the securities unit of the U.S. attorney’s office, he served as chief of the national security unit. In 2003, Schmidt spent nearly two years in Sarajevo, where he tried the first war crimes case in Bosnia and Herzegovina’s new state court. He is also an adjunct professor at the University of California Hastings College of the Law.
