D&M Concrete Co Inc was founded in 1960 by brothers Marv and Duane Knipfer with a simple idea — deliver quality projects through hard work, honesty, and craftsmanship. Four generations of family have helped build D&M into the company it is today.
Brothers Marv and Duane Knipfer started D&M in 1960 with one promise — quality projects through hard work, honesty, and craftsmanship.
As the years went on, more family members joined the operation. Today, four generations of the family have helped build D&M into the company it is today. We are still family owned. We are still pouring concrete the right way.
We focus on residential concrete flatwork — driveways, walkways, patios, garage floors, and new construction flatwork. Based in Madison, Wisconsin and working across Dane County, close to home means we stay on schedule, run jobs the right way, and stand behind every pour.
The people running the jobsite and the office, every day.
Dan started in the field. He worked his way up to foreman on large projects, then took ownership of D&M at 38.
Today, at 66 with 48 years of concrete experience, Dan is still on the jobsite. Hands on, every project.
Sean grew up around the business. He joined the office at 22 to handle estimating and operations.
Today he oversees quality control and lead estimating — the person you sit down with on a pre-construction walk-through.
To deliver exceptional workmanship and a genuine, family-driven experience — the same values that have guided us since 1960.
