The entrance to the Church Office and "S" Classrooms is that the very end of the one-way driveway, as you're coming down the hill towards the exit. You'll park in that lowest area of the parking lot and follow the sidewalk into the building. During events, the door will be open (with a green light on the keypad), otherwise, for security, you can ring the doorbell during Office Hours to be let into the building. This entrance is at the top of the map below, between S1 and the Conference Room.
