You're Invited
Duininck Centennial Open House
Join us at the Willmar Civic Center on Saturday, July 25th from 11am – 2pm to help us celebrate a century of strength. Program begins at 12pm with food provided for the first 1,000 people.
100 Years. Four Generations. One Purpose.
Building Strong Communities Since 1926.
Duininck was founded in Prinsburg, Minnesota in 1926 by three brothers with a team of horses and a belief that good work, done right, builds something lasting. A century later, we're a fourth-generation, family-owned construction company operating across the Midwest, Texas, and Southeast in heavy civil, asphalt, ready-mix concrete, and golf course development. We've outlasted depressions, adapted through industry transformation, and grown without ever leaving behind what made us. The principles that built the first road are the same ones we bring to every project today: quality work, lasting relationships, and a genuine commitment to the communities we serve. One hundred years in, we're just getting started.
