In 1964, at the age of 25 years old, Paul Lagasse Sr. was a hard working union carpenter with the vision of becoming a successful business owner. He made the decision to purchase his first rental property at 15-17 Cossett Street in Waterbury where he would have to work nights and weekends in order to keep his union job during the day. This first purchase was the beginning of Lagasse Apartment Rentals.

Over the next 47 years, Paul's love for real estate flourished with the help of his two sons Paul Jr. and Vincent. Hard work and dedication allowed the trio to acquire 27 more properties which have been awarded multiple beautification and lifetime achievement awards from both the City of Waterbury and the State of Connecticut. The business is still operated on a day to day basis by all three, along with the help of Paul Sr.'s grandchildren. The Lagasses pride themselves everyday in keeping their buildings affordable, clean, and well maintained.
