Chris Warner is a serious climber -- legendary, in fact. But even more impressive is how he has used his passion and knowledge to teach and inspire others. Chris has led more than 145 expeditions on the world's most forbidding peaks, including a successful trek to the summit of K2 in 2007. He is the founder of 'Earth Treks Climbing Centers' and 'Shared Summits', a non-profit that introduces school children to mountaineering. Chris speaks at events all over the world, sharing footage of his adventures and the lessons he has learned on the mountain. Oh, and he also co-wrote a best-selling business book called High Altitude Leadership.
