Hello! I am a 5th DAN Master in Traditional Tang Soo Do, a 4th DAN Black Belt in Traditional Okinowan Goju-Ryu, and a 4th DAN Black Belt in Traditional Okinowan Ryu Kyu Kobudo. Before retiring, I was a Doctor of Surgical Neuro-Oncology for 30 years, in which I also spent a breif time obtaining my Doctorate (Ph.D) of Sociology, then teaching a Ph.D. graduate class as a Doctor Professor of Sociology at a University in Northern California. I have also recently obtained my DMA (Doctor of Musical Arts) of Cello and Piano Preformance, and a Masters in Composition (And will soon be persuing a DMA as well). I have a passion for TRADITIONAL Martial Arts Theory, Philosophy, and History. I have been training in the Martial Arts from the age of three (51 Years), and will soon be testing for my 6th DAN Master's promotion in Tang Soo Do, and my 5th DAN Master's Promotion in Okinowan Goju-Ryu and Okinowan Kobudo. Replies will do much to oblige!! Thank You! Best Wishes, ~ Sa Bom Nim ~
