Take the Lake Washington Blvd exit from 520 and turn left at the end of the ramp. Follow Lake Washington Blvd through the Arboretum and turn right at the light on Madison. Follow Madison up hill and just past Trader Joe’s and look for 16th and Madison on your left as you crest the hill towards downtown. The office is a grey Victorian building directly across Madison from the 7–11. Parking is behind the building or on the street.
