Alan's interest in skiing began during the formative years of the sport in Colorado and continues today. It was through his efforts that Denver's City Council authorized the creation of the Winter Park Association, a non-profit agency, to operate the ski area independently from the City. He was elected Chairman of the Board of Trustees for the newly created Association and maintained that position until he stepped down as Chairman on Winter Park's 30th anniversary in 1969.

With Allan’s guidance, hard work and dedication, Winter Park grew into an internationally acclaimed ski resort with 18 chairlifts. In 1950, this once abandoned mountain park had only 3 T-bars and 4 rope tows. For 37 years he has been an active leader in the development of Winter Park programs, including an extensive expansion project, the fostering of slope grooming, the development of a nationally known jumping school, and the world's largest handicap program.

While at the age of 75, Allan remained an active member of The Colorado Arlberg Club of which he became a member in 1936. He has been an active supporter of the Denver Winter Sports Council, the 1950 FIS Championships, the United States Olympic and World Championship Teams and the Winter Park Handicap Program.
