So proud of our students today and grateful for this incredible Ohana. Not only did our students practice and train hard, but their supportive families stood by them (in the FREEEEEZING cold).

Happy holidays to you all. You should be proud of yourselves. And there is so much more to come!

Tomorrow is belt test day. Our students will show what they got, give it their all, and celebrate how much they have learned.

We have quite a few new students for whom this is their very first belt test. Excited to see them celebrate their accomplishments.

Drink water. Sleep well. And see you in the morning friends.
