Andrew began climbing at a young age in Germany, where his father was stationed. As a junior at the University of Central Missouri, he co-founded the UCM Climbing Club, and led trips all over the Midwest, to places like Horseshoe Canyon Ranch and Sam's Throne, Arkansas.

As a Captain in the 75th Ranger Regiment, during his third Tour in Afghanistan, Andrew found himself dreaming of climbing the cliffs surrounding the combat zones he was fighting in. While he loved serving his country, he knew the time had come to begin a new mission, that mission became RoKC.
