He started the Northwest Senior Hockey League in 1957 after a stint in the U.S. Army, and formed the Seattle Indians Senior Traveling Club two years later. During the 1960's, Andy was instrumental in the formation of the Pacific Northwest Amateur Hockey Association and the Sno-King Amateur Hockey Association; while the 1970s saw him aiding the Seattle Junior Hockey Association during the initial seasons. Andy also was in on the beginning of the Seattle Ironmen and Seattle Braves hockey clubs within his own Northwest Amateur Hockey Association (which was incorporated in 1979). He was also a minor official, trainer and backup goalie with the pro Seattle Totems for over a decade.

Andy served on USA Hockey's National Senior Council, and was active in the PNAHA circles. He was selected to the Seattle Hockey Hall of Fame in 1993, following Indians coach Don Ward and Ironmen mentor Howard Hughes (plus Northwest Americans had man Don Chiupka) into its membership files.

Andy's love affair with hockey dates back to his days as a teenage goalie in a pickup game with the legendary "Cyclone "Taylor in the old Vancouver Forum in the 1940s. Andy continued his goaltending career in recent seasons with the Braves and in numerous Senior and Old-Timers summer tournaments, where he remained tough to beat for skaters almost half his age. Andy's hockey committment and tradition is continued through his son, Dev Anderson, who has played with the Seattle Indians for 21 years.
