Meet Our Staff

Driven & Passionate Experts in their Field

Liberty Gymnastics Training Center has a dedicated team of coaches who are driven and passionate about gymnastics. Leaders in their field, the team has produced athletes that have reached the pinnacle of the sport and whom have developed many state, regional, and national champions and National Team members. Our staff’s primary goal is to provide a motivating environment that will encourage athletes to reach their goals.

Once a year, we send our coaches to attend the USAG professional training and certification program for proper coaching attitudes, progressions, first aid, safety, and spotting techniques. Through our own monthly in-house training program, our coaches continuously learn to become better than ever.

We train them not only on how to coach gymnastics, but educate them in other areas like: child development, psychology, and discipline. Our mission is to nurture your child as a whole person – body, mind, and spirit – so, we train our coaches to do just that.

We regularly evaluate and adjust our curriculum for the success of all our children and their varied learning styles. Through gymnastics and the spirit of "Achieving Together," Liberty Gymnastics staff and coaches, along with our member families, are building champions for life!
