Heartland Glass was started in 1980 by Ray Schueller, Mal Patton and Jim Scherer who all worked together at St. Cloud Glass before branching out on their own. Ten years later, in 1990, Heartland Glass was acquired by Brin Northwestern Glass Company, a nearly century-old glass manufacturer in Minneapolis, and Bill Sullivan was brought in as the manager. Being part of a larger company allowed Heartland Glass to negotiate optimal pricing from vendors permitting them to become much more competitive. As a result, Heartland Glass experienced tremendous growth and was established as one of the leading glazing contractors in the region. In 2007 Bill Sullivan bought out Brin Northwestern Glass and became the sole owner. Five years later, on July 1, 2013, Heartland Glass officially re-merged with Brin Glass Company in order to provide expanded opportunities for both customers and employees. “Employees from both companies know each other well and we share the same core values,” Bill said. The company has become an Employee Stock Ownership Plan (ESOP) which benefits employees now and going into the future, and Bill Sullivan is currently the President of Brin Glass Company.
“Clients choose to work with Heartland Glass repeatedly because of the quality of the experience they know they will have in working with us.” Bill said, “It starts from the initial call where a real person answers the phone, and extends to our friendly and knowledgeable staff who coordinate the efficient installation of industry leading quality products at a fair price. Hence our motto ‘Quality Clear Through’.”
