How do you know what your culture is in you academy and the community that it has become. This is a one of those moments that shows what an amazing community we have and the culture that is a result. We start our renovation/update today and so we had classes until 6:30pm. The mats were PACKED AND IT WAS A NOSTALGIC MOMENT! We had to completely t at down the mats and wall pads and move them out to make room for our new spring sub-floor. This was about 185 mats that are awkward and heavy. Our entire community stayed to help and we were completely gone in an hour. I can’t say how emotional satisfying it is to see something like this. A community that has been built and coming together to do so much. We are so thankful for you all and just wait until the product is finished. THANK YOU ALL SO VERY MUCH FOR ENTRUSTING US WITH YOUR JOURNEY! ...

It’s hard to talk about our Judo and BJJ instructors without sounding like we’re bragging. The plain fact of the matter is that we have one of the best teams of martial arts instructors you will find anywhere. Led by 4X Judo Olympian Brian Olson, our instructors are talented, accomplished, passionate and the kind of people you just enjoy hanging out with, because after all, although we take what we do very seriously, Judo and Brazilian Jiu-Jitsu is supposed to be fun.
