Sam Hargis

Shotokan Black Belt – 1st Dan

Hargis Senpai at an early age, I had a fascination with the martial arts and science.  At my college, Northeastern University, I got the opportunity to study and trained in Kung Fu.  Later on in life, I trained in Okinawan style martial arts which included Shorin Ryu, Goju Ryu, and Isshin Ryu. This was under the tutorage of Dr. Aiello, Hanshi of the Shito Kan organization.  At present, I am a Shodan in Shotokan Karate under the guidance of Sensei Oscar Silvera.  Also to note, I am a judge and member of the USA Karate Association.  

“Karate is not just about the physical, it is about forging the mind, spirit and body.”  It is design to make you into a better person, a better student, a better and stronger individual.  “Zensho - Live life without regret”
