Turn onto Sherwood Common Blvd
Turn right at the 1st driveway when seeing the Sherwood Office Center
Drive all the way to the end of the parking lot. The office is the 3rd building on the right with the sign Nguyen Psychiatry.
If you passed the Sherwood Comon Office Center sign and drive into the 2nd driveway (seen like white surburban) , then you missed the driveway.
