Kost Materials is a collaborative effort between Jeff Eberhardt and Tony Kost, who are both well-known in the ready-mix and aggregate industry in the Red River Valley.

Tony is recognizable with his work through Kost Brothers, which was a premier aggregate/ready-mix supplier in the Fargo/Moorhead area. For several decades Kost Brothers was the name to trust. After being out of the business for several years, Tony saw an opportunity for this new partnership and is quickly helping the business grow.

Jeff has been in the industry over 25 years working for his family owned business as well as leading multiple markets for large corporations in the Midwest.
