It is safe to say that Jeff Hennessy is the most effective trampoline and tumbling coach in U.S. history. He coached more international and national trampoline, mini-tramp and tumbling champions than any other coach in history, capitalizing on his 27-year stint as head coach at the University of Louisiana at Lafayette. Nine times he served as the Trampoline Team Coach in the World Championships, en route to honorary membership to the Federation International of Gymnastics and induction to the International Gymnastics Hall of Fame. He was featured in the Guiness Book of World Records and also was the Director of World Trampoline Championships.
