In May of 1967, Augustine "Augie" Calfo and Donald "Slim" Haight decided to go into business and built Calfo & Haight, Inc.  At that time there were three employess, Augie, Slim, & Gerry Calfo (Augie's wife).  Gerry handled the phones and the books. As the work increased, so did the number of employees.  Eventually, Augie's children grew up and two of them became part of the company, Nick and Dawn.  Augie's oldest grandson also became a plumber and joined the business. We are known for our honesty and friendliness with customers.  We are very proud of the fact that we still have some of the same customers from 1967. Augie and Slim have both passed on, but Nick, Gerry, and Dawn keep the legacy going.  We have long-time plumbing and HVAC technicians doing the outside work.  All of our employees are treated as family, that's why they stay so long.
