Anyone who's seen the Mile High Tumblers perform at events like Denver Nuggets games can testify to the thrilling nature of their aerial stunts: crazy twists and turns executed with and without the aid of mini-trampolines. But even better is the concept behind the spectacle. Thanks to founder Ozell Williams, who first made his name locally as a cheerleader for the University of Colorado Boulder and an Olympic athlete specializing in the rings, MHT serves as a youth program in which college-agers act as mentors for students in the early years of high school. Their goal: to reinforce positivity and build life skills while defying gravity. Williams is changing Colorado for the better, one flip at a time.
