Dianna Hume Sa Bom Nim has been training and instructing Soo Bahk Do for 40 years. She is a retired high school teacher/administrator who worked with students with Special Needs. Soo Bahk Do practitioners are expected to be scholars & practice Moo Do values inside and outside the Do Jang. The purpose of training is “to extend life beyond the normal span”.
