Coach David has been involved in gymnastics for the better part of half a century!!! He has coach men’s artistic, women’s artistic, and TNT throughout his many years in the sport. The best story I ever heard him tell was about the time he watched a coach get bitten on the butt by a camel at the famous Bela Karoli’s ranch. He has coached all levels of gymnastics, including international elite competitors and national team members.  In addition to being a fearless leader, he is also the Head Coach and Director of TNT Teams.
