Shortly after his success in the 1952 Olympics, Eriksen moved to the United States where he lived until his death. While ski racing for Norway, he was a ski instructor at Sun Valley in Idaho. Following his racing career, he was the ski school director at various resorts, such as Boyne Mountain and Pine Knob, both in Michigan, Sugarbush in Vermont, Heavenly Valley in California, Snowmass and Aspen in Colorado, and Park City in Utah. At the time of his death he was the director of skiing at the Deer Valley Resort in Utah, and also served as host of the "Stein Eriksen Lodge," a ski lodge in Deer Valley (not owned by Eriksen, but named in his honor). Eriksen was married to Gerrysue Eriksen then to Françoise and had five children: Julianna Eriksen, Ava, Stein Jr., Anja and Bjørn. He called both Utah and Montana home.
