John Dempsey Jr. is a martial artist, Shiatsu Therapist, and a Fitness Instructor Specialist. He began his martial studies in boxing at the age of 16, and soon moved on to Kempo. From there he pursued Budo/Ninpo Taijutsu, and later on, Goshin-jitsu. In 2001 he earned his Shodan in Goshin-jitsu, and in 2002 his Nidan, at which time John began formally teaching on his own. After spending 15 years competing in tournament circuits, John gave up competition to become more of a traditional martial artist. John had always found human anatomy fascinating, and he believes strongly that a good martial artist has expert knowledge of anatomy, (including weaknesses), and physiology. This belief has been reflected in his studies over the years in college/university courses in anatomy/physiology/pathology, and in his studies in reflexology, shiatsu, and Eastern meridian/medical theory. His focus has always been on private instruction. He prefers to teach this way, as it lets him focus on one person at a time for maximum results.
