Physical Address & Directions

We are located in the Sonoma Developmental Center near Glen Ellen. Please don’t try to use a mapping service to find us! Instead, go to the main intersection of Sonoma Developmental Center at 15000 Arnold Drive. Turn east, away from the historic brick administration building, onto Harney Drive. Proceed across a narrow bridge. IMMEDIATELY on the other side of the bridge, turn left into the small driveway and park in the lot. View map.
