From South (via I-495 from Route 2, 290, etc.):

Take exit 31 (Groton / Littleton Common).  Go left at end of exit ramp.  At the first traffic light (next to a Mobil station), go left onto 110 / Littleton Road.  We are located about 2 miles further, on your left (after you pass Kimball’s Farm on your right, and the 99 Restaurant on your left).  It's a large, 3-story brick building with a sign in front for 319 Littleton Road.

 From North (via I-495 from Route 3, I-93, etc.):

Take exit 32 (Boston Road).  Go left at end of exit ramp. Go about 1/2 a mile, then go right at the lights onto 110 / Littleton Road.  We are located about 2 miles further, on your right.  It's a large, 3-story brick building with a sign in front for 319 Littleton Road.

 From East (Route 2 or 2A):

 Take Route 2 West.  (There will be a sharp left turn in the road about 5 miles after 2 passes I-95.)  After this left turn, you’ll go about 2.5 miles to a big rotary where the state prison is (Concord).  At the rotary, you can take either the 2nd exit off the rotary (Rte. 2A; easier route) or the 3rd exit, which is Rte. 2 (if you're in more of a hurry). 

-- If you take Route 2A: you'll take it almost all the way to 495.  In Littleton, you'll come to a fork in the road just before the common.  Take the right fork; if you miss that, then take your next right (there will be a Mobil station ahead on your right).  Go north (right) on Route 110 (Littleton Rd.) about 2 miles (passing Kimball's Farm on the right, and the 99 Restaurant on your left).  Look for a large, 3-story brick building set back from the road a bit, with a sign in front for 319 Littleton Road.

 -- If you take Route 2:  Take it to the I-495 North exit, then take I-495 north to exit 31. Take exit 31 (Groton / Littleton Common).  Go left at end of exit ramp.  At the first traffic light (next to a Mobil station), go left onto 110 / Littleton Road.  We are located about 2 miles farther, on your left (after you pass Kimball’s Farm on your right, and the 99 Restaurant on your left).  It's a large, 3-story brick building with a sign in front for 319 Littleton Road.

 From West (Route 2):

 Take Route 2 East to I-495 North, then follow the directions above (“From South”).
