Ellsworth Builders Supply, Inc., was established in 1959. It was, and still is, a subsidiary of the Ellsworth Falls Lumber Co., Inc. The lumber company originally operated several small sawmills in the area. The supply company became a successful effort to diversify away from the troubles of the sawmill business. Ellsworth Falls Lumber Co. was backed by three families who summered on Mount Desert Island. Our <a>About Us</a> page has great information about EBS.
