As you enter the parking lot (large sign will note Boston North Technology), you will want to veer towards left and down small hill towards the back building that is labeled building C. You will then park wherever you see an open spot; there are DCF spots on right that you are more than welcome to use though you can park anywhere in the lot. You will want to enter building C's entrance and use stair or elevator to go to second floor. In either instance, you get off and turn left, you can't miss out entrance as we are first on the left off of elevator or stairs!
