When entering the university stay on Campus Drive, 
pass the big M circle,
pass the Stamp Student Union on your right;

When you approach the next stop sign, Campus Drive turns right, you should continue to go straight (road becomes Preinkert Drive). Proceed down the hill on Preinkert Drive, Mowatt Lane parking garage will be straight ahead.
You must then walk back up Prienkert Drive, and on your right side up a stairway with metal rails to a gated parking lot. This is the lot closest to LeFrak Hall.
Walk to the right until you see a set of stairs on your left going up the side of the parking lot.
Follow the stairs around LeFrak Hall toward the front. You will be in a courtyard which has several tables.
Upon entering LeFrak Hall, turn right, take an immediate left and follow the hallway until you are facing suite 1218. This is the main door to JPSM.
