When pulling in from the Chelmsford Street side, we are the mill building set back straight ahead. Drive past, with the building on your left until you reach the back parking lot.
Go in the front entrance from the ramp, and we are located upstairs (same entrance as Lowell Active Day).
We have an elevator inside to the right if needed!
