USSA History

---

In 1905, the U.S. Ski and Snowboard Association (USSA) began life in Ispheming, MI as the National Ski Association of America, a small organization representing five ski jumping clubs in the upper Midwest. Today, USSA is a truly national sport organization comprised of more than 30,000 athletes, coaches, officials, and volunteers supported by 100,000 parents, devotees, and supporters.



The National Ski Association was formed during a meeting of ski clubs from Ishpeming, MI, Minneapolis, Red Wing, MN, and Eau Claire, WI. Ispheming Ski Club President Carl Tellefsen, a Norwegian native, was its first president.

From its original focus on inter-club ski jumping competitions, the USSA has grown into the most diverse of any Olympic national governing body in America, supporting a wide range of sports including alpine, cross country freeskiing, freestyle, nordic combined, ski jumping and snowboarding. Those five clubs have grown into a network of more than 400 clubs, with thousands of coaches and volunteer officials and judges providing entry-level programs, athlete training, and competitions.

The USSA also supports elite athletes through the U.S. Ski Team, U.S. Snowboarding and the new U.S. Freeskiing program added in 2011.



Today, the USSA is based in Park City, UT at it's USSA Center of Excellence, a national training and education center opened in May, 2009.

The USSA continues to follow a vision of being best in the world in Olympic skiing and snowboarding, which was highlighted with a record performance at the 2010 Olympic Winter Games when 17 athletes won 21 Olympic skiing and snowboarding medals - more than any other nation!
