M. J. Connolly Co was founded in 1968 by Michael J. Connolly. Although his son William (Bill) became president in 1990, the company continues to be a family-run business, maintaining its high quality and standards. Bill Connolly continues the tradition of bringing you the best in fenestration systems. Our goal is to provide comprehensive guidance in open communications with architects, designers, engineers, and contractors.
