Our mission is to enhance the lives of children and their families by providing fitness and gymnastics classes in a challenging yet non-competitive environment.
Miss Kelly's Gym is a local, family owned gymnastics and fitness facility for kids. We offer gymnastics, dance and sport skills classes as well as children's Birthday Parties, Parents Night Out, Kids Camps and Open Gym.
We are located in the heart of Saint Louis County in Creve Coeur MO, just one mile west of Highway 270 and Olive Blvd in the Bellerive Plaza shopping center. The owners, Kelly and Matt Mertens, were born and raised in St. Louis County where they still live today. They have a 1 year old daughter named Aubrey (who is a regular at the gym) and a Yellow Lab named Luci.
Miss Kelly began taking gymnastics classes at the tender age of 2 and started teaching when she was just 15 years old. Miss Kelly has now been teaching for over 15 years and continues to love every minute of it!
