“The thing I enjoy most about jiu jitsu is it’s never going to become a simple 1,2,3 step formula. There will always be a new obstacle to overcome just how there is in life. We learn and grow together, and that’s what inspires me to continue on this journey.”

KATE KIMBLEY

Certified Personal Trainer
Strength & Conditioning Instructor
“When you become stronger, faster, and more agile, you gain an upper hand on your opponent. Sometimes your opponent is a person on the mat or in the ring, but other times your opponent is age, sickness, or even a job that keeps you sitting at a desk. I enjoy training people to be the strongest most capable versions of themselves so that they can have the upper hand both on and off the mat – in the ring and on the street – at the gym and at home.”
