Founder & Grandmasters

Grandmaster Jae C. Shin, the founder of the World Tang Soo Do Association, was one of the leading figures of martial arts in the world. Sadly Grandmaster Shin passed away on Monday 9th July 2012. He has left us a legacy, his dream, the World Tang Soo Do Association which we now have to nurture, promote and continue to build.

Grandmaster Robert E. Beaudoin started his study of the Martial Arts in 1960-61 while in the U.S. Air Force. He earned his Black Belt under Master Jae Chul Shin. 

On July 9, 2012, Grandmaster Beaudoin assumed the role of Grandmaster and Interim President of the World Tang Soo Do Association after the passing of our founder Grandmaster J C Shin. He was due to be promoted to 9th Dan Grandmaster at a ceremony later that year at the World Championships but received the honour posthumously with the iconic black and red belt being presented to his family. 

Grandmaster William R. Strong, 9th degree Grandmaster, received his current rank of Kwan Chang Nim at the US National Championships in Pennsylvania on October 9th 2021. 

Grandmaster Strong's martial arts career began in 1964 in Austin, Texas at the Jhoon Rhee Institute of Tae Kwon Do. 

In the early 1980’s, he became a member of the US Tang Soo Do Association and eventually received his Sah Dan Masters rank. Around the mid-1980’s he joined the World Tang Soo Do Association and Tang Soo Do has been his principal martial arts since that time but over the years he has also studied Hapkido, Aikijitsu, Aikido and Shotokan.

Boo Kwan Chang Nim Mujahid Khan is currently recognised as an 8th Dan (Pal dan 팔단) Instructor in the World Tang Soo Do Association. He has been training in the Martial Arts for over 48 years and has received many awards, including Instructor of the Year 1987 and many other commendations and appreciation awards from the Association.

Grandmaster Khan is the regional director for region #11, which encompasses Western Europe.
