Skiing was a passion to "Ad", as he is affectionately known, grandson of the founder of Coors Brewing Company. "Ad was an avid, enthusiastic and inexhaustible skier", his brother Bill Coors remembers. "He was involved not only in the sport of skiing itself but active in its development as a major Colorado industry and in the promotion of Colorado as Ski Country, USA." He imparted his love of the sport to his friends and family. A highly polished skier, he took every opportunity away from the brewery to hit the slopes on family vacations.

"He wanted to help those he really cared about to gain a taste of the sport he loved," recalls Cecily Garnsey, Coors' daughter.

Ad was instrumental in developing modern skiing in Colorado. He channeled his love and his resources toward establishing quality ski resorts in Colorado. He helped to found the Aspen Ski Corporation in 1946, and served on the board of directors until his tragic death on February 9, 1960. He was present at the opening of Sun Valley, became one of the earliest members of the Arlberg Ski Club at Winter Park in 1938, and was becoming involved with the development of Vail at the time of his death. Ad also helped to establish ski racing in the state, by bringing the World Alpine Ski Championships to Aspen in 1950 (serving as Finance Chairman), the first time the event was held in the US.
