Grand Master C.W. Oh was born on July 8, 1942 in Hwang Hae Do Province (now North Korea), and is a descendant of the Hae Ju Oh family. He immigrated to South Korea during the Korean War (1950 – 1953). Having studied the Martial Arts of Tae Kwon-Do and Hap Ki-Do at an early age, at the age of seventeen he joined the Korean Marine Corps as a member of the 118th Mortar Division, and taught the Martial Arts to the Marines.
After an honorary discharge, Grand Master Oh decided to move to Germany to fulfill his dream of traveling overseas. While working in the coal mines, he taught the German police forces and had a school of his own. While in Germany, Grand Master Oh met his wife and had his first son Inn-Seong, in 1971.
In 1972, he finally moved his young family to Canada and started Chung Oh’s School of Tae Kwon-Do in April of 1973 in Kitchener, Ontario. While there were other Korean Masters teaching Martial Arts, referring to their Schools as “Korean Karate”, Grand Master Oh was the First Korean Master confident and brave enough to inscribe “Tae Kwon-Do” on his school signage.
