Windows by Unlimited

In 1968, John Bellart, president and owner, made a bid to purchase a small window manufacturer in Green Bay, Wisconsin.  Already owning a successful electrical contracting business, and several bowling centers in the Milwaukee area, John and his partner saw a "window" of an opportunity.  They purchased the company, moved it to Milwaukee, and founded Unlimited, Inc.
