We are CLOSED on Monday, October 31st! Happy Halloween!

It is our goal at Giant Gymnastics to provide a warm and nurturing environment in which to educate our students of all ages on leading a fit and healthy lifestyle.


We strive to provide a safe and fun atmosphere for our students to learn, play, and grow through gymnastics and other related activities.  Giant Gymnastics and its staff members encourage their students to grow not only physically, but socially as well.  Members are given opportunities to build fit bodies and minds every day!

With 2 Locations, you will be sure to find the program that is right for you and your family.  Let us be the first to welcome you to Giant Gymnastics!
