Don DeBlieux- Assistant Coach


This winter will mark Don’s eleventh season as a junior comp coach with TUNA. Don enjoys having fun on skis with his junior athletes and hopes to foster a lifelong love of outdoor sports. He finds it very rewarding seeing them move up the ranks to become successful competitive racers and active adults. Don began skiing at Bousquet Ski Area in his hometown of Pittsfield, MA back in the days of rope tows, wooden skis, lace-up leather boots, and $1 night skiing. After his first day on the hill, he asked his parents if he could get a season’s pass! During high school, he competed in freestyle skiing (bumps, aerials, and ballet) throughout New England. Don began cross-country skiing during college at the University of Massachusetts. After graduating with a Master’s degree in Biology he moved to Nederland, CO. Don spent 10 years of his “early retirement” teaching and coaching cross-country and telemark full-time at Eldora Mountain Resort during which time he earned his level III certification in both track and telemark from the Professional Ski Instructors of America. Don moved to Utah in 2001. He has been a weekend ski instructor at White Pine Touring for the last nine years. Don has competed in over 400 races in triathlon, duathlon, running, and skiing since 1984, and is a regular competitor in the Wasatch Citizens Series. When not pursuing athletics, Don has helped to lead dozens of paleontological field expeditions in the western US, Egypt, Madagascar, Tanzania, Namibia, and China. Don is currently a Paleontologist with the Utah Geological Survey where he spends his summers scouring the deserts of Utah for dinosaurs and other fossils.
