In its quest to build out a well-rounded white-collar practice, Cooley has brought on prosecutor John Hemann from the U.S. Attorney’s Office for the Northern District of California.

Hemann most recently served as chief of the office’s special prosecutions and national security unit and the deputy chief of its criminal division. He joined Cooley’s San Francisco office as a partner in the firm’s white-collar practice, where he said he will work on the same kinds of matters that he handled as a prosecutor.
