John Sonnentag

John and Carolyn Sonnentag boosted a small, family-owned concrete and gravel company based in Marathon City from a modest manufacturer for masons and builders to an award-winning, industry leader of concrete construction and landscape products. County Materials Corporation — which the couple took over running from John’s parents — continues to make its mark 75 years later since its beginning, thanks to the tender-loving care the couple sustains. In addition to their work growing and expanding the business, John and Carolyn are incredibly generous to multiple causes like the University of Wisconsin-Eau Claire, Mayo Clinic and the University of Wisconsin-Stevens Point at Wausau.
