The name on both licenses

Callahan's Plumbing & Heating works out of Enfield, Connecticut. The name on both state credential records is Christopher Callahan. His customers call him Chris.

He holds two Connecticut unlimited contractor credentials: plumbing & piping, first issued 1989, and heating, piping & cooling, first issued 1993. Both are public records on the state's license database.

What the reviews add is a voice. Customers describe a plumber who calls back fast, quotes a price and then charges it, and explains what the job needs. One customer's phrase for it: “They are your old fashioned plumber!”
