About Us

My Story
Coach Jim Dowling
Founder and Director of JUMP TNT

"This TnT program became a reality as a result of being laid off from the corporate world in August of 2009. As a former high school and college gymnast, I have always wanted to do something with the sport of Trampoline for a long time. I now have the opportunity to share this sport with others. I used the Kangaroo as my logo because of how strong and high these animals jump which represents both Power Tumbling and Trampoline. "

"Now that I had the vision, I needed a gym to put in the program. After sharing a small place with a cheerleading gym in Johns Creek, for 6 years, it was now time to open our own facility and grow this sport!"

"Fitting in well with the Australian theme, Outback Steakhouse became one of our first sponsors. Soon after their grand opening in Roswell and Suwanee, SkyZone was a perfect fit as a sponsor as well. And then Get Air Trampoline park followed. All have been wonderful to work with and I encourage you to visit them as well."

"We offer Recreational classes for boys and girls ages 4 and up, pre-team, and we also have a very competitive Team by invitation. Come check us out. I've always said…
