Our History
William (Bill) Masters started Wm. Masters in the small town of Forrest, IL in 1976 as an electrical contractor. He soon added heating & air conditioning, and plumbing divisions, and relocated to Bloomington, IL in 1984.
As the business has grown over the years, with the addition of new locations and services, Bill's sons Ron and Aaron have joined the management & ownership team and continue to build the Masters’ legacy, which is built on trust and tradition that has been the core of Wm. Masters Inc.’s success. More than anything, they feel privileged to serve the families and businesses of Central Illinois.
