Grandmaster DANA R. Vaillancourt, 8th Dan


Dana R. Vaillancourt (Dan Bon #14676) has been training in the Korean martial arts for over forty-six years.  Dana received all of his Tang Soo Do dan ranks up to 7th dan from Grandmaster Jae Joon Kim (Dan Bon #38) and was promoted to the rank of 8th dan in Tang Soo Do by Grandmaster Chung Il Kim (Dan Bon #475).  Mr. Vaillancourt was an Executive Committee member with the World Moo Duk Kwan Tang Soo Do Federation (WMDKTSDF), a certified WMDKTSDF master instructor and received many Letters of Commendation and several Certificates of Appreciation from Grandmaster Jae Joon Kim.  He is currently a member of the World Tang Soo Do General Federation based in Seoul, Korea.

Grandmaster Vaillancourt is also no stranger to traditional and modern sport Taekwondo and also holds black belt certification and affiliations in Taekwondo with the World Taekwondo Chang Moo Kwan (Korea), Kukkiwon (Korea) and the United States Amateur Athletic Union's (AAU) Taekwondo program.  Mr. Vaillancourt currently has an 8th dan (#178) and international instructor certification with the World Taekwondo Chang Moo Kwan.  While familiar with the methods and merits of modern sport Taekwondo, Mr. Vaillancourt stresses the more traditional training methods of Korean self-defense and self-improvement, placing less emphasis on the sport aspect. 

Mr. Vaillancourt also has experience in Hapkido, having taught his first Hapkido program in Delmar, New York in 1989 and later continuing in South Dakota.  He was fortunate to continue to train Hapkido in Virginia while he worked in Washington D.C.  He maintains affiliations in Hapkido including The World Hapkido Martial Arts Federation in Seoul, Korea.

A long-time successful competitor and martial arts teacher, Mr. Vaillancourt has promoted many students to dan rank and several to master-level rank.  A student first, Mr. Vaillancourt continues to personally teach advanced classes in Huron, SD, trains on a weekly basis, and participates in martial arts seminars whenever possible. 

He has a Master of Science (MS) degree in cultural resources management and a Bachelor of Arts (BA) degree in both history and sociology.  An archeologist and architectural historian by profession, Mr. Vaillancourt recently retired from being the Federal Preservation Officer for the Natural Resources Conservations Service (USDA) in Washington D. C.
