The only parking lot at the corner of State St. and Liberty St. is the ESC building, where you will see our sign on Unit A. (It's a large tan building with 4 roll-up doors.) If coming over the Matthews Bridge get in left lane so when you reach the first stop light, look slightly left to see our lot and building. If coming East on Union St. from I-95, go past Main St. to Liberty St. and turn left, then immediately turn left into our parking lot before reaching the corner of State St. Please use the contact form to arrange a good visit time, as we are not always present during normal business hours but can generally meet you at your convenience.
