Sellin Brothers, Inc.

What Sellin Brothers, Inc. does

Sellin Brothers, Inc. is a second-generation, family-owned heavy civil construction contractor headquartered in Hawley, Minnesota, founded in 1947 by twin brothers Harold and Roy Sellin and now led by their sons (President Mark Sellin and Vice President Steve Sellin). The firm delivers highway reconstruction, underground utilities installation (sewer, water, and storm sewer), airport construction, municipal street grading, watershed construction, wetland restoration, and snow removal for federal, state, county, and municipal clients across West Central Minnesota and Eastern North Dakota. The company employs approximately 60 people during the peak April-to-November construction season and operates from a multi-building owned campus in Hawley that has been expanded multiple times since 1953.

The firm's equipment stack centers on heavy construction machinery — excavators, dozers, loaders, tractor hoes, skid steers, and backhoes — augmented by GPS and laser technology for finish-grade accuracy on civil engineering and highway projects. Sellin Brothers specializes in "wet work" and replacement projects that other contractors decline to undertake, leveraging more than 40 years of buried-utility installation experience, and runs a vertical-integrated shop plus equipment-sales side channel selling used assets (including a 1964 Caterpillar D9G) and corrugated metal pipe culverts at $5–$50 per linear foot.

The business model is project-based, with the majority of revenue generated through competitive bidding on public infrastructure contracts funded by federal, state, and local government appropriations. Pricing is quote-driven per project, with named municipal clients including the Hawley School District (current $53 million middle school), City of Moorhead, City of Valley City, City of Fargo, and City of West Fargo. Go-to-market is sales-led through public procurement, supplemented by direct retail of surplus equipment and materials and residential/commercial snow removal as an off-season revenue stabilizer.
