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.

Jack is a real life saver. Very Professional and easy to work with. He knocked out a large 20 page project in a couple of days and I feel very confident he estimated everything correctly. I will be using him for all projects that come up

Really enjoyed working together. My biggest praise would be the ease of reading his takeoffs as many other estimators we have worked with before it is a nightmare. Good attention to detail and responsiveness.
