Raising the bar since day one

Sr. Vice President Jim Heidorn and General Superintendent Paul Ingraham have been an integral part of K.R. Miller since Day 1. Their hard work, tenacity and friendship has shaped this company since our founding 30 years ago, and continues to set the tone today!

“When I started K.R. Miller Contractors in 1991, I knew there was a need for a company with a commitment to excellence. Three decades later, that’s still who we are.”
