We miss you already…please be safe.

Dear Olympia Gymnastics and Ninja City Families –

We hope this letter finds you and your family well. These are interesting times, though uncertain. We want to update you on how we are moving forward based on the latest information we have.

As you know, our gyms are now closed to all students for all activities due to the stay at home order issued by the County of St. Louis and Jefferson County through at least April 22, 2020. In light of this, we have made some decisions regarding classes for April.

Obviously, we will not charge April tuition for any of our families. We will continue to guarantee your spot in class for the duration of our closure, so that when we re-open, our students can come back to the same classmates and instructors as before. Families with annual registration fees due to renew in April will not be charged. For the few families that have dropped for April, please send us an email by March 31st if you would like to re-enroll, and we will place your child back in their class spot.

The uncertainty of these times is a little nerve-wracking. The one truth that everyone in our family of companies is that when we do re-open our doors, we will be better than ever. We will also continue to communicate with you all on a regular basis.

Our staff is truly amazing, and even during the closure are looking for ways to engage with all of you. Facebook is becoming one of the main ways we communicate with you – if you can, please follow all of our Facebook pages.

As always, please email us if you have questions or comments.

Please be safe and healthy and know that we miss our gym families.

Ballwin, MO — Olympia Ninja City in Ballwin has been around a little more than a year. It was simply a gymnastics facility at first but started ‘ninja’ classes a few years ago after the popularity of NBC's show American Ninja Warrior. Now, the ninja sessions continue to become more popular, proving that 'Ninja' isn't just a trend but becoming a competitive sport. Read more here
