My dad Leonard R Provost was born in 1922 Holyoke MA and he attended Chicopee trade school then he worked as a machinist at American Bosh in Springfield MA. In 1942, he enlisted in the US navy he was assigned to the USS Tuscaloosa he oversaw damage control during battle and saw action in both theaters of the war he was injured in action.

On his return to Boston, he married my mom.she worked as a bookkeeper for a trading company and he joined the plumbers union and in 1960 he and my mom formed Provost Plumbing company, my mom worked as a bookkeeper and dispatcher along with my dad they operated together the company until 1989 at which point they retired I began working for provost plumbing in 1973 I earned my journeyman’s license in 1977 and my master plumbers license in 1981. I married my wife in 1988 she began the tasks of operating the office arranging financing and managing operations. She is still the president of the company

I served as the plumbing inspector in Dedham MA. I am the former president of the Northeast Massachusetts Plumbing and gas inspector’s association. I began teaching at Newton evening school in 1990 until it closed. I am currently an instructor at central mass technical school. I am also an industry consultant and act as an expert witness involving litigation involving plumbing and heating.

In 2009, my son in law William R. Coombs joined the company. He had a great deal of construction experience and held a Massachusetts builders license before becoming a plumber. He is the holder of our corporate certificate with the commonwealth of Massachusetts and secretary and registered agent of provost plumbing. He holds a master plumbers license and a master sheet metal workers license. If you call for service you most likely will be speaking to him or myself. I’m honored and lucky that he decided to join our company and carry on our family business. My wife Delfina Nellie Provost is my best friend. She still acts as president of our company. She is an Air Force Vietnam veteran.
