About AMKM Gymnastics

Named after its four coaches, Amanda, Meghan, Kelsey, and Molly, AMKM Gymnastics began as a gym just for them thanks to their parents, Terry and Susan Arentz.  Their dedication and commitment helped start the tradition of gymnastics excellence that continues today!


Our Mission
AMKM Gymnastics strives to provide gymnasts the opportunity to develop their talents in a safe and positive environment.  Every gymnast deserves success and we help provide that opportunity! 

Safe Sport Commitment

AMKM believes in providing a safe environment for all of our students and as such follows the USA Gymnastics Safe Sport Policy.

Our coaching staff not only has a valuable background to provide great instruction but each coach truly cares about providing the best experience for each and every gymnast we see. Our coaches are not just working to help gymnasts get new skills, they are dedicated to helping gymnasts become confident and successful individuals in and out of the gym!
