About 3TI

Texas Tumbling and Trampoline Institute (3TI), Inc. is owned by Bill and Lisa Gandy. Our business opened September 1, 2001. We relocated to the present facility in December of 2005.  

A great team

A wealth of experience

Bill received his coaching degree from Sam Houston State University followed by a Bachelor’s in Physical Therapy at Texas Woman’s University in 1987.


Lisa was a former collegiate gymnast and national floor exercise champion that earned her Master's Degree in Physical Therapy from TWU in 1987 as well. She was the first gymnast inducted into the TWU Athletic Hall of Fame in 1995.  

Today they have both served on the national coaching staff coaching Team USA for USA Gymnastics at the Can-Am Cup, Canada Cup and Pan Am Championships.  


They currently serve as Co-Chairs of the USA Gymnastics Trampoline & Tumbling Education Committee. Both Lisa and Bill have a passion in working with children and trying to make a difference in their lives.  

The Gandy’s have a wealth of experience to draw from as they have 16 national champions and coached their daughter Sarah through a very successful gymnastics career earning her a classification as an official World Class Gymnast by the Federation of International Gymnastics. In her career, Sarah won 6 national titles, 3 international titles and a bronze medal in the World Age Group Competition and another bronze medal as a member of the Sr. Elite National Team at the World Championships in St. Petersburg, Russia.
