Our Story

Building on 40 years of Kansas City expertise, we deliver integrated commercial door, hardware, and specialty product solutions—getting the job done right the first time.

Design Supply Doors was originally founded in 1984 by a husband and wife team, Philip and Mary Stowe. These two created a unique company committed to faith, family, and doing the “right” thing for employees and customers. After a decade of second-generation family leadership under Rebecca and Toby Stowe, Design Supply Doors joined IOS, uniting two Kansas City legacy companies under one roof. We now deliver fully integrated Division 8, 10, and 28 solutions—combining our founding values and trusted expertise with expanded capabilities and seamless collaboration. One partner, endless possibilities.

Through our unwavering commitment to customer service and quality work, Design Supply Doors – now an IOS Company has developed a reputation as a trusted subcontractor in the commercial building industry. Today, we’re a team of Door Nerds who loves to have fun while getting the job done.
