50 Years of Company History
Gonthier Concrete has been a locally and family-owned business since it was founded over 50 years ago. We began with a mission to serve our customers with high quality work, integrity, and professionalism.
Gilles Gonthier started in the concrete business as a partnership in 1969. By 1986, Gilles branched out. Working side by side with his son, Gary, he transformed the company into Gonthier Concrete Foundations.
Gary grew up working with his dad after school and during summers and weekends. He learned about the business inside and out. In 1988, Gary was trusted to take on a leadership role, meeting with builders and homeowners to review plans, prepare proposals, and oversee the crew to ensure job sites were ready.
In 2004, Gary purchased the business from his father. In 2008, Gary incorporated the company and it became Gonthier Concrete, Inc. We've been an accredited member of the Better Business Bureau since 2012. Check out our A+ rating!
