COVID-19 Update (May 4, 2020):
We have been closely monitoring developments in our area and around the country concerning the COVID-19 situation. Based on information available to us, we initially paused our operations through April 6th. In light of Governor Baker’s subsequent directives, we will extend that period through May 18th. If circumstances change, we will adjust accordingly. But, for now, we look forward to seeing everyone in a couple of weeks.
For our Class/Program Participants: Session Three will remain paused for the duration of the closure (stay tuned for the date we’ll resume ninja and gymnastics classes). So, you will still enjoy a nine-week session. Session Four will commence as soon as Session Three concludes, with the date of our year-end show(s) TBD. Under these unusual circumstances, we’ll be providing maximum flexibility on make-ups once things get going. Check our website for some great discounts if you’re registering for Session 4 now.
For members of our indoor play facility: We will pause your membership, with the remaining term re-commencing when the facility re-opens.
If you have a party scheduled before we resume admission to the public, we will be contact you to identify alternative dates/times.
We thank you for your understanding, and we apologize for any inconvenience. Together, we can knock down the Corona-virus and get back to having fun!
Questions in the meantime? Shoot us a message on Facebook or leave us a message if we don’t catch your call. We can’t wait for you to visit us again and see all of the work we’ve done around the facility to get it ready for you.
Thank you!
