Hello Everyone,

We are one step closer to our “new normal” 😊 I just contacted the city and got permission to start doing outdoor classes!! So, starting tomorrow we will be holding our new class schedule (see attached) outside on the lawn area in front of the school. Students will need the following:
Water bottle
Mask (we have them available for purchase here at the school)
Warm weather clothing (shorts, karate t-shirt and belt)

In order to adhere with restrictions we will still need to limit the class sizes so you will only be allowed to attend those classes you have registered for. If you have not yet done so please reach out and let me know which days you’d like to commit to. We will also still be ZOOMing every class so for those who choose to stay home you may still attend class virtually and receive class credit.

I am beyond thrilled to be able to see everyone in person! Please review the schedule and let me know if you have any questions.

Thank you!

Good evening Everyone, I wanted to let you all know I dropped by the studio on my way back home and I’m thrilled to announce that it is untouched 🙏🏾❤️ I had a very sobering drive home as I say all of the businesses boarded up with messages spray painted on them like:
My heart is truly broken for our community but it has been absolutely wonderful to see all the ways in which people have come together to help each other out. We will get through this and our community will be stronger than ever!!

With regards to the ZOOM classes as of right now we are planning to proceed with the full schedule starting tomorrow. The codes for the classes can be found in the app in the new modified schedule PDF’s but I will attach them for your reference. If the 8:00 curfew is applied tomorrow we will not be holdin the last two classes. That way staff can make it home on time. Thank you all for your resilience and please let me know if you have any questions!
