The Washington State Chapter (previously the "Cascade" Chapter) is led by volunteer leaders elected by Sierra Club members who live in Washington.  The State Chapter and local Groups work on local and statewide issues with a small paid staff in the Seattle office.

The Northwest Regional Staff are employees who are directed by the National Sierra Club. They are located in Seattle and Spokane and work on national issues in our region with the help of volunteers.
