Ravenswood ends at Middlefield Avenue. Turn left at the second traffic light, on Willow Road. Proceed about 2 miles down Willlow Road, over the 101 freeway. Turn right into Willow Park. Once in the parking lot, turn left.
Nuance is in the second building on the right.
Missing the Nuance entrance is easy . There are 2 traffic lights past Nuance on Willow. The second traffic light is at the end of the road, where Willow hits SUN, and the first is not far after the missed turn. If you reach either of these last 2 lights, make a U-turn at the light and take the left turn just west of the first light. Once in the parking lot, turn left.
