Our Past 

Twin City Glass is the very definition of a family-owned and -operated business.

Established in 1964 by Don and Nancy Weinholtz, the company originally focused primarily on the automotive glass market. However, when Don and Nancy’s son Mark joined the family business in 1981, he launched a bath enclosure and shower door division in order to meet consumer demand. Then, in 1983, Don and Nancy’s other son, Rich, joined the business to head up the commercial division, which specializes in automatic doors and storefronts. Daughter Beth also joined the firm full-time in 1995, as the company’s treasurer.

Our Present 

Today, Twin City Glass is a full-service glass shop serving a variety of residential and commercial customers, as well as builders and contractors, in the Buffalo Niagara region. We offer you top of the line bath enclosures and shower doors, as well as expertly crafted glass and mirror products.

Despite the company’s impressive growth, we remain committed to the simple, old-fashioned fundamentals that helped Twin City Glass achieve success over four decades in business – hard work, integrity, and providing you with excellent customer service on every project, large or small.
