More Than Martial Arts — A Life System
At YK Taekwondo Academy, we believe martial arts is the most powerful self-improvement system available. Founded with a mission to inspire and empower every student, we offer a training environment where people of all ages — from 3 to 94 — can grow stronger in body, mind, and character.
What sets us apart is our individual-paced approach. Your progress is always measured against your own personal best — never against your peers. This creates genuine confidence and sustainable growth, whether you are a child learning focus for the first time or an adult building resilience for the demands of modern life.
From our Kids Martial Arts classes to our Family programs, every student at YK Taekwondo Academy receives expert instruction, personal encouragement, and a supportive community that celebrates every milestone on their journey.

Head Instructor & Founder
Master Youngmin Kim
World Taekwondo International Referee | Masters in Sports Management
I'm Master Youngmin Kim, Founder and Head Instructor of YK Taekwondo Academy. My Taekwondo journey began with a full scholarship at Joongbu University in Korea, and it has taken me to competition floors, referee panels, and coaching benches across the world.
As a World Taekwondo Federation International Referee (Level 2 Poomsae & Sparring), I have officiated at the World Grand Prix in Paris, Wuxi Grand Prix in China, US Open, Costa Rica Open, Mexico Open, and Kim Unyong Cup G1. As Sparring Head Coach of Team Elite National Team, I have trained and coached athletes across CA, AZ, TX, NY, and NJ for local, state, national, and international competitions.
But beyond the titles, what drives me every day is watching students transform. I believe martial arts is not just a sport — it is a complete system for developing the mind, body, and character. Whether you are a child just beginning your journey or an adult looking to build real confidence and self-defense skills, I will meet you exactly where you are.
At YK Taekwondo Academy, every student progresses at their own pace — measured only against their personal best. There is no comparison to others, no pressure to keep up. Just consistent growth, real encouragement, and a community that celebrates every step forward.
I also bring experience in college admissions counseling and mentorship for student-athletes, and I currently coach the Sports Taekwondo Club at New York University. I am proud to serve the Old Bethpage and Long Island community, and I look forward to welcoming you to the YK Taekwondo Academy family.
