Avery was one of the first students to join Blur MA after our school made the shift toward more realistic, holistic self-defense training. Since then, she has come a long way — not just in what she can do, but in how she approaches every challenge on the mat.

Her kickboxing is strong, she has done very well on her belt tests, and she brings a steady willingness to learn every time she trains. Avery shows the kind of focus and coachability that help a junior student grow into a leader.

What stands out most is the way Avery elevates the kids around her. She trains with purpose, sets a positive example, and helps make the room better for everyone in it.

Congratulations to Avery Wong, our July 2026 Student of the Month.

Junior Spotlight

Leonardo Umpierre

Juniors · On the Path to Junior Black Belt

Leonardo has moved up in rank and is working toward his Junior Black Belt. That path is earned one session at a time, and he keeps showing what it looks like to stay committed even when life gets busy.

He continues to make the Saturday workouts a priority despite having other activities competing for his time. He shows up, pushes himself, and brings a never-quit attitude to the mat.

Like Avery, Leonardo elevates the other kids in class. His effort sets the tone, his consistency is noticed, and he reminds the people around him that progress comes from refusing to give up.

Keep climbing, Leonardo. Your Junior Black Belt journey is just getting started.

Aiden's martial arts story began with private lessons, when even speaking comfortably could be difficult because of a tongue-tie. After surgery and steady work, he continued to grow — first into a standout student, then into a member of the demo team, and eventually into an instructor.

He followed the example of his older brother, Elgin, but built a coaching style that is completely his own. Aiden brings high energy to every class and has a natural way of connecting with young students. He understands that kids learn best when they are engaged, moving, and having fun.

That does not mean the work is easy. It means the work is memorable. By turning practice into play, Aiden helps students in the Junior Warriors and Warriors programs build skills, confidence, and a genuine love for being on the mat.

From private lessons to demo team to instructor, Aiden is proof that steady growth can become real leadership.

Holistic Self-Defense

I grabbed these photos at Oak Valley's Back-to-School Night. I felt happy seeing families gathering at the start of a new school year, and sad that architects now have to design schools with safety in mind in ways previous generations did not have to consider.

That reality is part of why we teach holistic self-defense: safety is not only about a physical response. It is also about awareness, emotional readiness, empathy, and the choices we make long before a crisis.

Two weeks ago, I was teaching the Juniors class exactly what they asked for: how to think about a school shooting. It is a subject I dread, especially having a wife who teaches as well.

A large component of our system is based on holistic self-defense, so I was less than excited to teach something I felt was important but not as important as mental and emotional stress inoculation. Then, after a lesson from Coach Blauer, I realized that we cannot teach someone to prepare for something they do not take seriously. We worked through drills designed to improve the students' mental speed if the worst ever happened.

After class, my nine-year-old, Ri, was shaken. She told me I should not be surprised if she snuck into my bed that night. She did not — but I was ready for her to. I was shaken too.

Even so, one of the most important parts of the SPEAR System shines through when we talk about holistic self-defense and school violence.

D1

Detect

Pay attention when something changes, and learn to recognize when someone may be isolated, troubled, or in need of support.

D2

Defuse

Practice regulating yourself, moving through stress, and making choices that lower tension instead of adding to it.

D3

Defend

Build the courage, awareness, and practical options to protect yourself and to become a safer bystander for others.

D1 — Detect

I asked the kids to give examples of who they thought might become a school shooter and what that person might look like. Their answers were familiar: kids who do not fit in, are bullied, are socially isolated, or are being antagonized by others.

I told them that detection means taking the next step and paying attention to who those kids are. When you already recognize that someone seems isolated or troubled, a meaningful change in behavior may be easier to notice. That awareness can help us make safer choices and bring concerns to a trusted adult.

D2 — Defuse

If someone has reached the point of planning an attack, they may already be far beyond the point where another student can simply defuse them. Instead, I emphasized how important it is for the kids to learn to defuse themselves: to work through the cycle of behavior and activate righteous indignation for themselves, not only for their friends.

The kids felt confident that they could act if a physical threat demanded it. So I gave them a harder question.

D3 — Defend

I reminded them that a child in the United States is more likely to die by suicide than in a school shooting. If they are genuinely concerned about school violence, there is another timeline of harm they should be prepared to recognize as well.

If they see a kid who is socially isolated or struggling, reaching out — even when it feels uncomfortable — can be the safer and more courageous choice. I challenged them to consider whether the courage they imagine using in a crisis can also be used to approach the loner and risk a little social discomfort by being kind to someone everyone else ignores.

It is easy to talk about protecting ourselves in a situation that is possible but may never happen. Reaching out to another person is an opportunity we have every day.

One of the things I value about being a SPEAR Coach is being an options facilitator. I do not tell people what to do. But I do try to be as kind as I can be, mentally and emotionally, to everyone. Those are the kinds of students I think will not only be safer themselves, but will become courageous bystanders for someone else.

Self-defense is not only about what we do when we are in physical danger.
