Humble Beginnings…

Southwestern Manufacturing Inc. first opened their doors on October 5th, 1994. Initial owners John Gagnon and Vince Schiller opened up shop at 849 Walker Road in Windsor, Ontario, Canada. Starting with less than 20 employees and sharing a small shop with another company, SMI has come a long way to where they are today. This constant growth and progression is attributed to the extensive knowledge, experience, and care that SMI incorporates into every project.
