Choong Jae Nim Master Chun Sik Kim began his training in Tang Soo Do when he was 8 years old in Busan, South Korea.  After much determination and under Grandmaster Young Suk’s tutelage, he earned his black belt two years later.  Knowing he wanted to dedicate his life to spreading the teachings of this authentic martial art, Choong Jae Nim Master Chun Sik Kim began teaching Tang Soo Do in Songtan City, South Korea and at the Osan Air Force Base, South Korea in 1967.  During this time, he received several invitations from various instructors, including Supreme Grandmaster Hwang Ki, to come to the United States to help spread the traditions of Tang Soo Do.  In May 1972, Choong Jae Nim Master Chun Sik Kim immigrated to New Jersey under the sponsorship of Grandmaster Shin, also an instructor at the Osan Air Force Base.  After relocating to Pittsburgh, Pennsylvania, Choong Jae Nim Master Chun Sik Kim formed the International Tang Soo Do Federation™ to continue his goal of spreading the authentic Tang Soo Do teachings he learned when he was a child.
