Grant DeShon

Grant DeShon, P.E., is a commercial sales representative for Coryell Roofing. Grant generates sales opportunities for the company in the commercial/private sector in Missouri.

Grant grew up on a dairy farm in northwest Missouri, so he grew up working. He attended the University of Missouri where he earned both a bachelor’s and master’s degree in agricultural engineering. After graduating, Grant worked for a civil engineering consulting firm and a company that manufactures wastewater treatment equipment. Grant brings to Coryell the technical skills of an engineer as well as communication skills he uses to help clients understand what Coryell Roofing can do for them.

Grant agrees with Aristotle: “We are what we repeatedly do. Excellence, then, is not an act, but a habit.”  His life is guided by the Bible as the highest authority. He believes that in living its main principle of loving God and loving people, a person finds success!

Grant wanted to work for Coryell Roofing because he saw the how the company values team members. He is also a John Maxwell admirer. As such, he appreciates that Chris and Kelly Coryell are John Maxwell coaches, and he wants to be part of a team led by the Maxwell principles.

Grant married his college sweetheart, Laura, and together they have three children: Isaiah, graduating from Mizzou in December of 2022; Kalyn, beginning her senior year in 2022; and Nathanial, starting 3rd grade the fall of 2022.

When not working or busy with family, Grant enjoys shooting, landscaping, and tending livestock.
