2nd Degree Black Belt - BJJ

After watching the first UFC's in the early 90's, Sam began searching for a practical martial art that was grounded in effective techniques rather than forms and board breaking. After some disappointing experiences with more traditional martial arts, he began training submission grappling in 1997 in his garage with friends. In 1998, he began his formal training in Brazilian Jiu Jitsu. From that first group class experience, he was hooked and has been passionate about BJJ ever since. Sam is committed to helping students connect with Jiu Jitsu and teaching effective technique, new and old. He enjoys coaching FJJ competitors and can be heard loudly “advising” and supporting students at the local, national, and international tournament scene. In 2012, as a brown belt, he won the gold medal at the International Masters Championship in Rio de Janeiro, Brazil. Coach Kim is a 2nd degree Black Belt belt in Brazilian Jiu Jitsu and teaches both adults and children at FJJ.
Sam has been involved in the development of mixed martial arts and the growth of combat sports in the area for many years. He was the matchmaker for the Mixed Martial Arts Championship (MMAC), the first ever professional MMA event held in the nation's capital at the DC Armory. Leading up to the event in 2007, he worked with the team, the commission and local officials to get MMA officially sanctioned in the city.
Sam holds a Masters degree in Clinical Social Work (MSW) and is a Virginia Certified Substance Abuse Counselor. Outside of the Academy, he works in private practice as a mental health therapist working with adolescents and adults. Sam is the proud father of three children. His son, Matthew, began in the kids program at age 6 and is now a blue belt in Brazilian Jiu Jitsu. Matthew is an assistant coach with the FJJ's kids program helping the next generation learn and grow to become successful young men and women.
