Instructors

	Master Brian Costello, Founder Master Costello has been practicing martial arts for over 32 years. He started the school in 1984, teaching primarily Tang Soo Do and Jujitsu. As the school evolved, he began adding full contact fighting and reality based combat training to the curriculum. In the early 90's he integrated these styles to form the Jung Su School of Martial Arts. Having trained in Tang Soo Do, Shotokan, Jujitsu and Kick Boxing, he continues to teach and learn alongside his students. Having instructed thousands of martial artists over the years, his personal philosophy is to work hard each time you step into the Dojang and strive for constant improvement.
