San Antonio Jiu Jitsu

We aim to provide a safe and open space for students to learn the art of Brazilian jiu jitsu through self defense first and then all of the extra benefits that come with learning jiu-jitsu. We aspire to create an environment where students of all walks of life can learn how to be successful throughout their journey on the mats as well as off the mats.

What to expect in a training session or class: Kinetics is the change that happens in the forces inside and outside of ourselves. Jiu jitsu is kinetics working in a martial art form. In my Kinetics classes we will practice movement, breathing, mindfulness, and meditation. I am here to be of service within the realms of Kinects, and my hope is the experience will create the change that is intended for you.
