"Amazing classes for both jiu jitsu and thai boxing. The coaches are great and have several competing champions, and the head coach is a former UFC champion. Everyone is very wholesome and welcoming. I came in off the street and found it very easy to jump in and start training for the first time in my mid 30s."
