As an Adaptive PE teacher in the 1980’s, Gregg Baumgarten saw there were no competitive opportunities for many of his students who had physical disabilities. So he founded what is now Arizona Disabled Sports with his good friend Mark Grant. As pioneers in adaptive sports, the two would also create Desert Challenge Games and the first ever National Power Soccer Tournament in the USA. Gregg would direct a number of regional and national competitions and assisted with the formation of many other organizations and competitions. He would serve on the board of directors of Disabled Sports USA and as board chair of Adaptive Sports USA, the two predecessor organizations of Move United.
