In 2000, our school’s founder, Master Tim Calvin purchased Pallen’s Martial Arts from one of his instructors, Professor Joseph Pallen. At that time, we only taught Senkotiros Arnis (Philippine stick and knife fighting) and Kajukenbo, which is a hybrid street fighting art comprised of Karate, Judo and Ju-Jitsu, Kenpo Karate and Chinese and Western Boxing.

In 2005, Master Tim changed the name of the school to Delta One Martial Arts and Fitness Center and he incorporated Brazilian Jiu-Jitsu and Kickboxing into our curriculum.

In 2014, Master Tim saw the necessity for yet another change, modernizing our system to fit the self-defense needs of today’s society and creating an exciting program designed to help people mature, develop and grow to reach their full potential.

To complete our well-rounded martial arts program, known as the Kajukenbo “Urban Self-Defense” System, we included Krav Maga, a highly effective self-defense system created and taught by the IDF (Israeli Defense Forces) into our curriculum. We saw that by blending key concepts and techniques from the different martial arts programs we taught into one system, it made that system highly effective and extremely practical for today’s urban environment. Our students are now capable of defending themselves standing, on the ground, against multiple attackers and attackers with various weapons, such as knives and guns. They are also capable of utilizing sticks and knives as a practical and realistic means of defending themselves.
