One Coach, One Gym, One Standard
Jarred McQuitter, Head Coach & Founder
Jarred built J’s Kickboxing Club around the training that shaped his own fight career: fundamentals first, discipline always, and no shortcuts on technique. As a former competitive fighter, he coaches from experience, not a certification binder.
Every member trains directly under Jarred, whether it’s a first class or a hundredth. That’s the whole model: small enough that the coach knows your name and your left hook.
