222 St John Street #216, Portland, Maine
Turn in at Margarita's (242 St John)
Go around the big building keeping it on your left side.
Use the entrance that faces the parking lot. Then take the elevators up to the 2nd floor, suite 216.
(It's in the same office as Maine Community Acupuncture)
NOTE: On the weekends the doors facing the street are locked so even if walking you'll need to use the doors on the backside of the building
