From the Taconic:

Heading North: Take the Underhill Avenue Exit. Make a right off exit onto Underhill Avenue. Take Underhill Avenue for 2 miles to light. Go straight through intersection to next light (Shell Station on left; Yorktown Highway Department on right) and turn right (continuing on Underhill). Take your next right on Front Street. We are the 4th building down on the left-hand side #1776.
