Master Changmook Kang
Master Changmook Kang began his Taekwondo journey in South Korea, training on the Jayang Middle School and Dongsung High School Taekwondo teams before earning his Bachelor of Sports Science from Hanyang University.
As a Kukkiwon-certified 6th Dan Black Belt, he brings over 30 years of world-class expertise and a deep understanding of traditional Korean martial arts to every class. His training at the highest levels in South Korea — the birthplace of Taekwondo — sets him apart from any instructor in the Inland Empire.
His teaching philosophy centers on leadership, respect, perseverance, self-discipline, courtesy, and goal setting. Taekwondo is more than kicks and punches — it's a vehicle for building character, confidence, and resilience that extends far beyond the dojang.

Our Philosophy
The Five Tenets of Taekwondo
These principles guide everything we teach. They're not just words on a wall — they're the foundation of how we train and how our students live.
Respect
Every class begins and ends with a bow. We teach students to respect their instructors, their peers, and themselves.
Perseverance
The path to Black Belt is not easy — and that's the point. We teach students to push through challenges and never give up.
Integrity
Doing the right thing even when no one is watching. We hold our students to the highest standards of character.
Self-Control
True strength is restraint. Our students learn to control their emotions, their actions, and their bodies with precision.
Indomitable Spirit
The courage to stand up for what's right and the determination to achieve your goals, no matter the obstacle.
Our Dojang
