roundhouse (formerly alamo ranch martial arts) · our story

every kid deserves an instructor who knows their name.

I'm Mr. G, your Alamo Ranch neighbor. For 20+ years, I've helped San Antonio kids get stronger, sharper, and more sure of themselves.

just a conversation about your kid. that's all it is.

my story

it started with a knock on the door.

I was 12. A neighborhood buddy invited me to his martial arts class.

I said yes. That one yes changed everything.

The mat gave me somewhere to be after school, and people who expected more from me than I did.

At 16, I was helping teach. It was my first job. I already knew what I wanted to do with my life.

then. a 12-year-old who just needed someone to say "come try it."

now. saying "come try it" to the next generation.

next. this little guy is Noe — my grandson, my newest training partner, and the only student on the mat who calls me grandpa instead of Mr. G.
all in

i went all in.

I earned my psychology degree at UTSA, right here in San Antonio, to learn how kids think, what motivates them, and why some lessons stick.

I saved every dollar and opened a tiny school.

20+ years later, I still train four days a week. I'll never ask your kid to work harder than I do.

And fair warning: I'm a product of the 90s. You'll hear old school hip hop on the mat.

old school discipline. new school teaching methods.

home

this isn't just where i work. it's home.

I live in Alamo Ranch. Our students' families are my neighbors.

And today, my grandson trains on the same mat. The next generation of our family, learning what I learned at 12.

Every kid who walks in gets what I got: a place to belong, and someone who believes in them first.

why roundhouse

why we changed our name.

For years we were Alamo Ranch Martial Arts. Same families, same mat, same instructor.

As we grew, we rebuilt how we teach from the ground up: new research-based drills, a 1-on-1 plan for every student, and a character system that reaches home and school. It deserved a name that matched.

New name. Same heart. If you trained with us before, welcome back.

what i believe

kids rise to the level we expect.

belts are earned, not handed out.

Every stripe means your child actually did the work. That's what makes them proud of it.

fun is how kids learn.

Lights, music, games, real challenges. When kids love class, you don't have to drag them. They drag you.

character counts more than kicks.

Students earn stripes for how they act at home and at school, not just on the mat.

every kid is different.

So every kid gets their own plan. One size fits one.

the village

it takes a village. we're part of yours.

Most families don't live in villages anymore. Today the village is home, school, and the mat.

We work with all three. Teachers send us notes. Parents tell us about wins at home. We celebrate them on the mat. Your child grows everywhere they show up.

testimonials

the people who notice aren't the ones we teach.

★★★★★
"Nicholas has been demonstrating first-time listener behavior — when it's time to bathe, brush his teeth, get dressed, go to bed, even turn off games and television. He's doing all of it without even mentioning getting a stripe for behavior."

"We want to point out how much improvement Jordan has shown lately. His behavior has improved — we no longer get extra notes from the teacher in his folder. At home, he's helping his sister, completing chores, and following directions."
