Your Premiere Glass Service



Serving New York, Massachusetts & Connecticut

Calvin A. Sheldon worked for a glass business in Long Island where he then had dreams of owning and operating his own business. In 1960, he took a leap of faith and moved back to Hillsdale, New York and began Sheldon Glass Service in his house garage, eventually advancing to commercial property. Then in 1988, Calvin and his son-in-law, Mike Keefner, became incorporated until Calvin’s retirement three years later in 1991, where Mike then took over the family business.

58 years later, Sheldon Glass Service is still standing strong because of you.
