Donald and Nancy Grimm
Donald and Nancy Grimm started Grimm Mold & Die Co. in 1965 with just one milling machine in their home workshop. After a few years of success, they purchased a 5,000 square foot building on US 20.
In 1980, he bought the building that formerly housed Sam's Market in Rolling Prairie, IN. 1995 saw the addition of another 5000 sq ft space at this location. In 1998, Don's son Tim took over the operation of the company.
Unfortunately, Donald passed away in early 2018. Nancy is still enjoying her retirement here in Indiana.
Tim Grimm
Tim began working with his father, Donald, at the young age of 14. Over the years, he honed his business, mechanical and design skills.
After high school, Tim continued working with his father while obtaining his Industrial Design degree.
When not running their business, they enjoy visiting their grown daughters Taylore & Morgan, spending time on their boat on Lake Michigan and going to events with their two Bernese Mountain Dogs.
