2017 Hideo "Mizo" Mizoguchi - “Coach Mizo”, as he is known throughout the gymnastics community, competed in the Japanese Elite Program in the early ‘70s before coming to the United States in 1974. He attended graduate school at the University of Oregon while assisting the Oregon Men’s Gymnastics Team. He holds a bachelor’s degree from Chukyo University in Japan and a master’s degree in Physical Education from the University of Oregon.

In 1977, Coach Mizo started a Junior Boys Program at the National Academy of Artistic Gymnastics in Eugene, Oregon. In 1979, he joined the Junior Olympic National Team program as a member of the Junior National Coaching Staff. Of the original members of the Jr. National Coaching Staff, Mizo is one of the few still actively involved in coaching the Junior Olympic Boys Program. While in Oregon, he served as Regional 2 Chairman from 1979 – 1983.

In 1984, Coach Mizo was selected from among the members of the junior coaching staff to step into the position of USA Gymnastics Junior National Technical Director, replacing his mentor, Mr. Watanbe who had returned to Japan. He served as the USA Gymnastics Junior Technical Director under the leadership of Mr. Robert Cowan, the men’s program director, until 1994. During this 10-year period, he also served as the Chairman of the Junior National Coaching Staff, the Chairman of the Age Group Competition Committee, the assistant of Educational Project for the FIG, under Mr. Bill Roetzhiem, and served as a Delegation Leader to several countries for international competitions.

While working at the USAG Home Office in Indianapolis, Indiana as the Junior Men’s Technical Director, he married Kellie Kavanagh in 1988. They have a son, Tyler, now 27 years old.
The family moved to Houston in 1994 where Hideo directed the newly built Brown’s Gymnastics. In 1996, he and Kellie opened their own gymnastics facility – Champion Gymnastics Academy in Houston. They moved the business to Katy in 2005 and have been running a very successful gym for the last 20 years. In 2014, they built a 30,000-sq. ft. training facility in Richmond, Texas with a new business name – Fun & Fitness Gymnastics.

Mizo is a regular speaker and lecturer at many of the regional and national events including GAT, Future Stars and Regional and National Clinics throughout the country. Today he continues to impact young gymnasts’ lives with the experience and wealth of knowledge that he has in gymnastics.


2017 Mike Spiller -“As a boy, I was always tumbling around Austin with an occasional trip to Crenshaw’s gym to jump tramp. I moved to Houston as a young teen and became a member of Bartosch Bounders Gymnastics Team in Bellaire, Texas. A couple of my teammates at the time were Beau Biron, Charlie Teas and, of course, Gerald Bartosch. We did Clown Diving and local parades. Later, I moved to Austin continued to tumble and trampoline during my high school years with Gerald Bartosch.
My military duty from 68 to 72 / USMC – Marines took me on one tour in Vietnam. I was the only US serviceman to build a trampoline in a combat zone – Marble Mountain, Vietnam 1970. Soon after getting out of the service, I took a full-time job at the Laguna Beach Boys Club as the Program Director for Fitness and Sport, and started a tumbling and gymnastics program there. I got married, and went on to coach gymnastics at the Vista Parks and Recreation Department and the Vista Boys Club.

I returned to Houston and in 1976 Gerald and I opened Gym-an-I Gymnastics in North Houston. Some of the coaches there were Ann Paschal Rangle, Rick Newman, Jim and Cheryl Jarrett, Jim Culhane, and Jeff Martin.

I later went to Switzerland and began to coach the Jr. National team there in the Luzern area with Lilo and Stephan Oberli. Many of the girls I trained made the 1985 World Championship Team in Montreal. After Switzerland, I took a head-coaching position at Santa Fe Gymnastics in New Mexico with Glenn and Betty Herring. I stayed there for a while and then took a job as head-coach on the Big Island of Hawaii with the Waimea Gymnastics Club. It was here on the Big Island that my “Games of the World” business took root.

After I left the Big Island, I came back to Texas where I continued doing workshops and trainings with schools, YMCAs, Boy and Girls Clubs, Experiential Learning groups, Day Care programs and the like. My Games of the World business eventually lead into Summer Camp Counselor Trainings. I have been presenting these trainings for over 20 years now and they seem to be very well received.

My current project is what I call my Stackrobats or Gym Stackers. I still do a lot of training, but find time to make these little, wooden stacking gymnasts for all to play with. I like to think that at one time I made good gymnasts while coaching and now I’m still making fun gymnasts at the age of 67.
It has been my joy to be a part of the Texas gymnastics family for the last 57 years. I have made so many life-long friends in this sport. My life has been enhanced due to gymnastics and if I had it all to do again – yes I would change a few things, but for the most part, I would do it all over again.”


2016 James Jeffers - has been blessed to be married to wife Robin for 27 years. He has two adult sons, Austin and Alex, a daughter-in-law Margaret, and soon to be daughter-in-law Kristin. Along with wife Robin, James has owned and operated J&R Gymnastics for over 26 years with locations in New Braunfels, Seguin, and San Marcos. His Finance degree from Texas A&M provided business training but his gymnastics training was learned on the job as he had no involvement in gymnastics growing up. The success of their gyms has enabled James to travel, hunt, fish, whitewater kayak, ski, scuba dive, and enjoy life in Texas and many different parts of the world. He actively serves his church and community with his time and resources. James has served the GAT board and its membership for 18 of the past 19 years.

Starting out as GAT treasurer in 1996, he supported the education director’s recommended move to pay speakers market rates which has enabled GAT to continually attract the best presenters in the nation. Taking over exhibit hall duties in 2002 and continuing still today, James was able to increase vendor attendance by 25% and increase overall revenue by over 30%. These increased earnings have helped to keep membership registration fees low. As Chairman of GAT since 2005 he has had the privilege of working with a great team of people who provide outstanding education and meeting opportunities to our GAT members at a cost that cannot be rivaled. A great conference at a great value equals great attendance and the great attendance means all conference costs are covered. Due to great management, we have been able to avoid a rate increase for the past 4 years. James’ business success is due in part to some disciplined financial practices but the larger success is due to the awesome well-educated staff that makes gymnastics fun to students in the communities they serve. His company annually brings 15 to 20 staff members to GAT because the power of education and the quality of learning that occurs each year at the GAT convention pays rich dividends. Not growing up in the sport, many of James’ early coaching skills were learned at GAT, and that education continues to this day. Elected 2016.
