SAN FRANCISCO — Jenny Durkan, a former U.S. attorney for the Western District of Washington, will open a new Seattle office for Quinn Emanuel Urquhart & Sullivan on February 2.

Durkan, a Seattle native, will join Quinn Emanuel’s white-collar and corporate investigations practice and will chair its cyberlaw and privacy group. She said she was uncertain of her next move when she resigned as U.S. attorney in September after five years in office.
