Our Story

Mandy Miller, co-owner and head coach, dreamed of owning a gym since she took gymnastic classes as a little girl.

In 2010, her dream became a reality when she and her parents, Billy and Lisa Miller, opened MEGA. Bringing over 40 years of combined experience of business, marketing, and entrepreneurship as well as an additional 18 years of Cheerleading and gymnastics, MEGA has brought a variety of developmental and competitive programs to the community's children.

What Customers Say

Our daughter walked in the door a shy little girl hoping to learn how to do a back handspring. She quickly mastered that skill and also became a member of their first cheer team which led to a love for the sport. After her 7-year competitive cheer career at MEGA she accepted a position on a cheer team at a Big 12 School! Beyond the various skills she acquired through the years, she also learned many other valuable lessons about leadership, accountability, hard work, persistence, and teamwork.

MEGA is amazing! I was looking for a program to really develop my daughter in her gymnastics skills as well as confidence. MEGA provides both! They coach to a program that teaches our children key concepts in life like confidence, how to be a good leader, being responsible, respectful and more. I am so appreciative of the flexibility MEGA provides as well as the trust I can put into them with my child.


MEGA is perfect for the littles to burn energy off, socialize, and learn to follow instructions other than from mom! Our girl looks forward to each class & is always practicing what she learned in class!
