          Clint began climbing in 1997 and was immediately hooked. For him, climbing is much more than a sport, it’s a physical, aesthetic, and emotional outlet.
          Clint has guided and instructed rock climbing in Colorado since 2001, as he
           enjoys helping others experience the beauty of the mountains and believes the full climbing experience can only be achieved through a thoughtful balance of passion, adventure, calculation and risk mitigation. When he’s not guiding or hanging out with his wife and two children, Clint can be found scampering around his second home–Eldorado Canyon.

                  Mark started climbing in Chicago on the tallest Indoor climbing wall in the country, where he would run laps until his fingers could no longer untie his knot, unlace his shoes or unbuckle his harness.  Within months, Mark’s fingers had recovered enough for him to head to Alaska with the American Alpine Institute, where he completed several first ascents on unnamed mountains.  Soon after, Mark left Chicago for Boulder, where he now helps build and strengthen connections within the community by providing indoor and outdoor instruction to beginner climbers and those new to the Front Range.
