Founded by Douglas Rehbein, Treasure State Concrete, Inc. is a family-owned business operated by three generations of Rehbein’s and Flathead Valley locals alike. 
TSC started out with crushing and trucking, then expanded to make and deliver concrete and asphalt. Eventually, the owner took years of experience as an owner and former operator at riverside contracting to establish his own earthwork and paving operations.
Today we provide work for public, commercial, and private jobs alike.
