How We Started

Owner Harry Illenz grew up surrounded by the building and construction business. His father and grandfather were carpenters, so while other kids were playing with LEGOs, he was pounding nails with his dad and granddad. 

While attending school for engineering, Harry decided he wanted to start his own business and in 2003, HMP Builders was formed in Lockport, NY.
