Master Terrell, Chief Instructor.

6th Degree Black Belt . 31 Years in the Martial Arts

Starting on the East coast of New England, I started studying the art of Shaolin Ch’uan Fa (Kempo Karate) as a child in 1985. Almost five years later, in December 1989, I was promoted to 1st Degree Black Belt. It was then I knew that Martial Arts was more than just a hobby. It became a desire to experience Kempo to the fullest and to gain a deeper understanding of the techniques. I knew that I wanted to teach the Kempo System to others. About a year and a half later, I receive my 2nd Degree Black Belt.
From December 1990 – 1994, I served our country with the United States Marine Corps.
