Dian Nissen is a multiple-world-title trampoline athlete, AAU All-American, health and fitness expert, and entrepreneur.
Growing up in Cedar Rapids, Iowa, and the daughter of George Nissen (WAS 2001 T&T Legend), Nissen’s involvement with competitive trampoline began at an early age. Competing internationally at the first World Age Group Trampoline & Tumbling Games in 1972 at the age of 12 and becoming the U.S. National Trampoline champion in 1977 in all three trampoline events: Individual Trampoline, Synchronized Trampoline, and Double Mini-Trampoline at the age of 16. Nissen competed at multiple World Age Group Games between 1974 through 1978, winning world champion titles in Trampoline, Double Mini-Trampoline, and Synchronized Trampoline. She won multiple Nissen-Eterna Cup titles in Switzerland, placed 4th at the 1976 World Trampoline Championships, and became the Japanese National Trampoline Champion in 1977.
During these years, she helped her father, George Nissen, promote his invention of the modern trampoline by performing in hundreds of exhibitions and educational trampoline clinics throughout the U.S. and worldwide.
A graduate of the University of Iowa, Nissen holds a double Master of Science degree in Health Education and Exercise Science. She is a certified Pilates personal trainer, Flexibility Coach, and an ACE-Gold Certified Group Fitness Instructor and Health Coach. In 1994, Nissen founded her company, Ageless Fitness, to promote health and wellness for people of all ages and abilities. She is a women's health advocate and expert on women's wellness, fitness, and achieving maximum health. In 2014, Nissen founded the Nissen Trampoline Academy specializing in recreational and competitive trampoline.
Nissen continues to give back to the sport of trampoline gymnastics through her work with consumer safety organizations as an advocate of trampoline safety, education, and awareness. She co-authored a Trampoline Park Risk Management & Operations book focusing on improving core safety practices, supervision, and enforcement for the industry. Nissen is a member of the Board of Directors of the World Acrobatics Society, and the National Association of Intercollegiate Gymnastics Clubs (NAIGC), and is also co-chair of the NAIGC Trampoline and Tumbling Rules Committee.
Inspired by her father’s quest to improve his invention of the modern trampoline, Nissen continued to seek out fitness trampolines that were safe and of the highest quality. The bellicon® fitness trampoline met her criteria and she is a certified bellicon® fitness trampoline instructor through the bellicon® Academy.
Nissen remains one of the most successful competitive trampoline athletes in history and continues to coach trampoline. She is still bouncing to this day — where the switch from daily competition trampolining training changed to fitness trampolining and educating the world on “all things trampoline."
