At the local level, the Girl Scouts of Northern California are broken down into smaller governing bodies called service units (in some areas formerly known as Associations). Each service units has a personal contact at the council office called a Community Development Director.

Click the links below for information about each service unit, cities served, membership statistics, CDDs (Community Development Directors), and on some pages, local community events.
