Why parents call us

You already tried telling him to walk away.

It worked once. Then it stopped working. Most parents who call here are not looking for a trophy. They are looking for their kid to stop feeling helpless.

He freezes

Something happens at school and he doesn't know what to do with his hands, his voice or his body. That reaction is trainable.

He's on a screen all day

School lets out and the tablet comes on. He needs a place to be tired, present and around other kids his age.

He's shy and stays quiet

Confidence doesn't come from being told he's great. It comes from doing something hard, on his own, twice a week.

What your kid actually learns

Control. Not toughness.

Most situations a kid runs into never needed a punch. They needed him to stay calm and stay in control.

That is what Jiu-Jitsu trains. How to handle someone bigger without hurting them and without getting hurt. It is the reason first responders and military families in San Antonio have trained on these mats since 2006.

One of our adult students is a child psychologist who works with aggressive kids. When a 14 year old came at her, she controlled him safely on the ground. Nobody got a scratch. That is the skill we teach.

The free trial class

Here's exactly how the first class goes.

No surprises, no pressure, nothing to sign at the door.

Pick a time

Choose a class time that fits your week. It takes under a minute.

Show up early

Arrive ten minutes before. T-shirt and shorts is all he needs. We provide everything else.

He trains, you watch

He trains with kids his own age and size. You stay in the room the whole time.

Then you decide

We talk after class. If it's a fit, we'll show you the options. If it isn't, no hard feelings.

Class times

Right after school, five days a week.

Kids and teens train in separate classes, back to back. Your 6 year old is never on the mat with a 16 year old.

Before you visit

This is a school, not a gym.

  • Everyone is in uniform. Full gi, school patch, shirt underneath. No exceptions.
  • The mat rules are posted on the wall and they are enforced. Kids know what is expected before they step on.
  • Only black belt professors teach. No colored belts running a class here.
  • "Relentless and Always Loyal" is painted on our wall for a reason. It is what we ask of every student, starting at age four.

Straight answers

What parents ask us first.

My kid is really shy

Perfect. Shy kids do better in the group than one on one. Within three classes he'll know names and he'll have a partner waiting for him.

He's only 4. Is that too young?

Four is exactly where we start. Parents have brought kids in at three and a half. The class is built around movement and games, not drilling.

He has never done a sport before

Half the room started the same way. Nobody is behind on day one.

Is it safe?

Jiu-Jitsu has no striking. Kids train with partners their own size, on matted floor, supervised by a black belt professor the entire class.

What does he need to bring?

For the free trial, a t-shirt and shorts. If you enroll, the uniform is part of the starter package.

Do you have a discount for military or first responders?

Yes. Ask us at the front desk when you come in for the trial class.

Book the free class. Watch it. Then decide.

Kids classes run Monday to Friday at 5:00 PM. Pick the day that works for your week and bring him in.
