Two Offices.One Standard of Work.

Headquartered in Fredonia, KS. Second office in Tulsa, OK. Building across the region.

Where We're Based

Full project operations.
Not satellite outposts.

Koehn Construction Services was founded in Fredonia, KS and has operated there since 2003. Our Tulsa office opened to serve the growing demand for KCS’s work in Oklahoma and surrounding markets. Both offices run full project operations – not satellite outposts.

The work doesn’t stay close to home. We’ve built in Kansas, Oklahoma, Missouri, and beyond. If your project is in our region, we can build it.

Regional construction is relationship business. You want a contractor who knows the territory – the subcontractors, the inspectors, the local codes, and the clients who will tell you honestly how a project went. That’s what two decades in this region builds.

Don’t see your market listed? Contact us – if the project is a fit, we’ll tell you.
