We have one in the Philadelphia area in Chestnut Hill. His name is Steven Erisoty, and there is a listing for him in the phone book. Let me know if you need his #. I have sent many customers to him and they all seem to be satisfied.
I can speak for WestLake Conservators. We have a great relationship and work well together; located about 2 miles from my shop. I send them conservation, cleaning, and restoration, and they send me framing, and I cut their specialty mats on the Wizard.
