“Kung Jung Mu Sul here at Rogers Ranch is, by far, the best Martial Arts school I've ever attended. I felt welcomed here from the first time I called, to my first visit, and even now as a student. The instructor, Aaron, has a coaching philosophy more akin to that of a mentor.”

Why KJMS Rogers Ranch
More than a martial arts class.
A mentorship in discipline, focus and character.
Most students walk in never having thrown a kick. Classes stay small and personal, ‘I love that the classes are not too crowded,’ one parent told us, so Mr. Aaron and his team can actually coach every student, not just supervise a room.
Mentorship, not just coaching
Mr. Aaron Delagarza's philosophy is mentorship over coaching. Reviewers describe him balancing fun and discipline while keeping students motivated, never with degrading sarcasm.
Real Korean lineage
Kung Jung Mu Sul traces to Korea's royal-court martial tradition. Mr. Aaron has trained since age 7 and studied directly under Grand Master Soon Tae Yang at World KJMS HQ.
Character built into every class
Discipline, focus, confidence and leadership are woven into the curriculum itself, not an add-on to the kicks and punches.
A welcoming, non-crowded community
Classes stay small enough that no student gets lost in the room, and families say they felt welcomed from the first time they called.
Kung Jung Mu Sul, explained
Never heard of it? Here is what the art is, and what your child (or you) actually learns.
A royal Korean martial art

Self-defense for every age

Member story
From nervous to confident
One KJMS parent, Kelli, described her daughter as having struggled with confidence issues and nervousness before starting.
Classes stay small and personal, ‘I love that the classes are not too crowded,’ another parent told us, so instructors can actually coach every student.

Mr. Aaron Delagarza
Training in Kung Jung Mu Sul and Tae Kwon Do since age 7
Mr. Aaron Delagarza started training in Kung Jung Mu Sul and Tae Kwon Do at age 7, right here in San Antonio. He went on to lead the original San Antonio branch of KJMS Texas, training 300+ students a week, and studied directly under Grand Master Soon Tae Yang at World KJMS HQ, later teaching KJMS in South Korea and across the US as a curriculum consultant.
Before returning to his roots, Aaron spent time in a corporate leadership role, training and leading teams at a global technology company. That experience shaped how he coaches today: as a father himself, he's learned to be motivating and supportive at once. He calls himself "a true product of the product," and believes in the value of martial arts training through childhood and beyond.
“A true product of the product.”
Community
Part of something bigger than a belt.
One reviewer commutes all the way from Helotes just for the instructors at Rogers Ranch. Families gather to cheer on belt tests and promotions, “your hard work has not gone unnoticed” is a phrase you'll hear a lot here.
Join a school where classes stay small enough that everyone, from four-year-old Tigers to adult black belts, actually gets known by name.
