From 2007 to 2021, Mr. Willis was a pro service specialist at Lowe's, where he became one of the few in his district to estimate blueprints and calculate all necessary materials for contractors—a responsibility many avoided due to liability concerns and the specialized knowledge required. Notably, Mr. Willis's proficiency in this area earned him recognition as one of the top ten pro service specialists in a region comprising 100 stores.

Before his tenure at Lowe's, Mr. Willis contributed as an engineering support designer at General Motors from 1989 to 2007.

He also spent two years at Mid America Design before serving as a contract designer for Guide Corporation. In addition to his technical roles, Mr. Willis has experience as an educator, having joined the faculty at Newcastle High School and demonstrating his commitment to sharing his knowledge and mentorship.

A passion for academic excellence drove Mr. Willis to pursue a Bachelor of Science in practical arts from Ball State University, which he earned in 1975. He subsequently sought a Master of Science in practical arts from the same institution, which he completed in 1979. Driven to serve, he has consistently sought opportunities for civic engagement and has volunteered to help build a church in the Dominican Republic and participated in construction ministry efforts in Kokomo, Indiana. Additionally, Mr. Willis sponsors English school tuition for children in underserved regions across the globe, underscoring his dedication to supporting education and community development internationally.

Mr. Willis has earned an enduring reputation for his expertise in design estimation—a skill that has set him apart throughout his career.
