NSAA's mission is to support members in their pursuit to operate thriving and sustainable businesses and deliver exceptional experiences. The National Ski Areas Association is the trade association for ski area owners and operators. It represents over 300 alpine resorts that account for more than 90 percent of the skier/snowboarder visits nationwide. Additionally, it has nearly 500 supplier members who provide equipment, goods and services to the mountain resort industry. NSAA analyzes and distributes ski industry statistics; produces annual conferences and tradeshows; produces a bimonthly industry publication and is active in state and federal government affairs. The association also provides educational programs and employee training materials on industry issues including OSHA, ADA and NEPA regulations and compliance; environmental laws and regulations; state regulatory requirements; aerial tramway safety; and resort operations and guest service. NSAA was established in 1962 and was headquartered in New York, NY. In 1989 NSAA merged with SIA (SnowSports Industries America) and moved to McLean, Va. The merger was dissolved in 1992 and NSAA was relocated to Lakewood, Colo., because of its central geographic location. NSAA is located in the same office building as the Professional Ski Instructors of America and the National Ski Patrol in Lakewood, Colo., a suburb west of Denver.
