Corey Rabenberg

Chief of Staff

At Summit, we know that our employees are the very backbone of our company. That’s why we put our very best in charge of them. As Chief of Staff, Corey makes sure that every Summit employee has everything they need to be successful. Corey grew up just down the road in Armour, SD and spent 28 years serving in the South Dakota Army National Guard. Corey says he never thought he’d find the sort of camaraderie the military offers, but has found that spirit alive and well at Summit. He and his wife have two grown kids and one about to leave the nest, which has provided him a bit more free time which he spends on his boat on the Missouri River.
