From Route 3, take exit 8. Take the offramp through two traffic lights and take a right on to Amherst Street (101A), heading toward Merrimack. Continue on Amherst Street until you pass Chili's Restaurant, which will be on your left. As you pass Chili's, make your way into the far right hand lane. At the set of lights after Chili's there will be a Shell Gas station on your left and PK's Garden Center (now closed) on your right. Do not go through this traffic light, instead turn right into Advanced Family Dentistry's driveway ( it runs parralell to PK's). We are located in a light yellow Ranch style building. Parking for our office is at the rear of the building and the entrance is closest to the street.
