"I have spent 25 years watching people discover they are more capable than they thought.That moment never gets old."

The practice started because I kept seeing the same thing.

People came to SIMA looking for self-defense skills, or just something different from the gym they had been going to for years. They left with something they did not expect. A calmer nervous system. A clearer mind. A sense of physical capability that changed how they moved through the world, and how they showed up in their work, their relationships, and their own skin.

My background is in Filipino Kali, Jeet Kune Do, Brazilian Jiu-Jitsu, and Muay Thai. But what has shaped me most as an instructor isn't any single discipline or credential, it's watching what these arts do to people over time. The anxiety that quiets. The confidence that builds slowly and then holds. The way someone moves differently after six months, and carries themselves differently after a year.

That's what I study. How stress lives in the body, how it hijacks decision-making, and how a consistent physical practice, one that actually challenges the nervous system rather than just tiring it out, trains you to move through pressure instead of being stopped by it. That knowledge didn't come from a textbook. It came from years on the mat, watching real people change.

Most of my students are working professionals in their 30s, 40s, and 50s. They are fit. They are successful. And they come here because something is still missing… the kind of calm, embodied confidence that a gym or yoga studio simply does not build. That is what this practice is for.

The arts I teach are a framework, not a prescription. Filipino Kali, Jeet Kune Do, Brazilian Jiu-Jitsu, Muay Thai…each one is a lens, a set of principles, a way of solving problems with your body and your mind. But no two people who walk through this door are the same. Different bodies. Different histories. Different reasons for being here.

My job is not to fit you into a system. It is to find the system that fits you and build a practice around the person you actually are, not the practitioner you think you're supposed to become.

The art serves the practitioner. That is the only version of this work I know how to do.

The martial arts are the method. What they build is the person. Every student who walks through this door is walking a path, and my job is to make sure the path is worth walking.
