About me
As Lead Estimator at CJR Construction Group in Kansas City, I specialize in takeoff, cost estimation, and change order management across commercial projects — including major works at KCI Airport and Omaha Eppley Airfield.
Working alongside JE Dunn, Turner, Paric, Centric, and Clarkson Construction has given me a clear understanding of what serious contractors expect from their estimates. PlanSwift and Bluebeam are part of my daily workflow, and every deliverable is built to hold up at the bid table — any trade, any state.
When I'm not estimating, I'm probably losing a soccer match.
