Duininck Companies

About Duininck Companies

Our journey began nearly 100 years ago with entrepreneurial beginnings in Minnesota road construction. We’ve been stretched by the challenges and filled with gratitude for the successes over the years. Organically and through acquisitions, we’ve grown into a family of companies, each with its own core focus, customer relationships, and unique reflection of our Duininck Family's values. Today, we are a diversified family business portfolio in water management, construction and materials, and real estate industries with over 1,000 dedicated employees at locations across the United States. Now in our fourth generation, we are energized to build for the future with a focus on people, values, and growth.
