Dian Nissen​

Dian Nissen has been involved with sports and fitness since her youth, where she trained daily in her father's gymnasium eventually becoming a multiple world-title athlete and competitor.

She is an AAU All-American, and was once concurrently the U.S. Women’s Trampoline champion in all three trampoline events: Individual Trampoline, Synchronized Trampoline, and Double Mini-Trampoline. In 2015, she founded Nissen Trampoline Academy, LLC in San Diego, California, USA.

Dian’s father was George Nissen, the inventor of the modern-day trampoline. Dian helped her father promote his invention of the trampoline and the sport of trampolining by performing hundreds of shows in the United States and around the world and competing in national and international trampoline events.

For decades, Dian witnessed the progression of the trampoline, double mini-trampoline, and tumbling including the evolution of equipment, rules, form and style, politics and most everything associated with a growing sport.
