Our Philosophy

Master Y Kim's World Class Tae Kwon Do(Master Y Kim's Martial arts School) is the leading provider of martial arts instruction in the St Louis, MO area. For over 30 years we have been teaching the martial art of Tae Kwon Do to children, adults, and families.

When we state that our goal is to teach the highest quality martial arts, it refers not only to high standards of technical skills, but to the character development and leadership skills that are an essential element of truly learning Tae Kwon Do. Therefore, our training includes skills valuable in daily life: focus, cooperation, self-control, confidence and respect.

We know from experience that training in Tae Kwon Do helps students in their personal and professional life. The positive character traits that develop will help them at work and school, at home and on the playing field.

Master Young Joo Kim was born in Seoul, South Korea. He started his Tae Kwon Do journey at age 5 in the Little Tiger program. At the age of 10, he received his first degree black belt. He started the Junior Instructor program at age 13. With this training, he learned how to become a leader, teach the students and memorize the different curriculum. He started the Senior Instructor program at age 15. He started teaching a couple classes per month and began to dream about having his own Tae Kwon Do School in the future.

He started on the sparring team at age 16. He began to learn more details about sparring and competitions, the technical aspects of sparring and the feeling of receiving a gold medal! His demonstration journey began at age 18 on the K-Tigers demonstration team. He began to learn weapons, tricking, gymnastics and started understanding the performance aspects and staffing for demonstrations. Master Kim had the opportunity to travel to the biggest Tae Kwon Do schools in the country!

He attended Sang Ji University which is in the top three Tae Kwon Do schools in Korea! The team received first place in the biggest Tae Kwon Do competition in Korea called Hanmadang.
