We’re just the right size.

Rahn Excavating & Grading is big enough to handle the big jobs yet small enough to provide personalized, hands-on service.

About Us


Rahn Excavating & Grading started in 1974 when Miles and Cele Rahn donated a parcel of their farmland for their son, Denny, to start his own excavating business. Miles was an active part of the company well into his 80s, and Denny remains at the helm to this day.

The company began with a 977K CAT Loader, a 350 John Deer Dozer, and a 3960 International Excavator, focusing primarily on improvement projects for local farmers. Today, Rahn Excavating & Grading services a variety of industries, including commercial, municipal and residential development, leveraging state-of-the-art, GPS-controlled equipment.

Despite more than four decades of experience and growth, Rahn Excavating & Grading has never lost touch with its roots. Denny’s son, Chris, serves as vice president, and the entire staff — an extended family — provides excellent, responsive service our competitors cannot match.
We are small enough to be nimble but big enough to tackle large, complex projects.

Key Staff

Denny Rahn
Denny RahnOwner & President
Rahn Excavating & Grading was Denny’s dream from the start. With more than 45 years of experience in excavating and grading, he has built a strong company with a legacy of successful projects. Denny’s role at the company hasn’t changed much over the years. He is involved with each project from start to finish. Denny splits his time between the office and running equipment. He takes pride in the company’s fleet and is happy to have an opportunity to “move dirt” himself whenever he can.
Chris Rahn
Chris RahnVice President
Denny’s son, Chris has over 20 years of experience in excavating and grading — not counting the time he racked up on machines and job sites since he could sit up. As vice president, Chris also plays an active role in all projects from bidding to finish grading. Chris completes all takeoffs and models in-house. If Chris isn’t running a bulldozer, you’ll find him at his laptop.
Jenn Wilke
Jenn WilkeCorporate Secretary/Office Manager
When you call the office, you can look forward to talking to Jenn. As Denny’s daughter, she spent much of her childhood tagging along with Dad while he moved equipment. Add her 13 years in banking and finance to that, and Rahn’s customers are always in good hands.
