Started by Benjamin (Put) Putnam in 1952, Putnam Service was build on a passion for customer service. Put had lead the Southwestern Adventist University maintenance department for over 20 years. From building a power plant to power the then college, to installing Keene's first fire alarm system Put was not afraid to tackle anything mechanical or electrical.
In the 1980's the gradual transition to new leadership saw Jere (Bugger) Putnam taking the lead. Under his leadership the company continued the expansion of commercial installation and service.
