Industrial Door Company

Gerry Sizer, Founder and President

Gerry Sizer started his garage door company in 1974 in his garage with $800 and a pick-up truck. He had three goals for his business:

  1. achieve $1 million in sales
  2. employ ten people
  3. make $100,000 profit


He reached those goals within four years. His operation outgrew what his garage could handle and Gerry moved into a 6,000 square foot facility in Coon Rapids. In 1978, with a loan and a promise from CMDC he was able to purchase the building he was leasing and make much needed improvements.

For a company that its founder thought would achieve modest success IDC has grown to be a $20 million company with 100 employees and has sold commercial and residential garage doors in twenty-two states, Kuwait, and China. IDC diversified into spring manufacturing with the purchase of a spring company, now Industrial Spring Company. With the help of CMDC, IDC now occupies five buildings and 200,000 square feet.

Gerry reflects on his relationship with CMDC, "They kept their promise. They have guided me through the process and kept the paperwork to a minimum." 

Gerry received CMDC's Lifetime Achievement Award in 2005. "I couldn't have built this business without CMDC and the financing expertise they provide. They are an asset to the community."

Gerry's philosophy for doing business is, "Respect people, your employees, your clients, your suppliers, everyone. CMDC is a company that matches that philosophy! They're great people, experts at what they do, and display great respect for their clients."
