Dr. Greg Steiner, 9th degree Chief Master
Dr. Greg Steiner, DC.
Dr. Greg Steiner, DC is now a 10th degree senior grand master in the Park System of Kenpo-Jujutsu and designated as the next in line 1successor for the Kajukenpo Kenpo-Jujutsu Association. Chief Steiner began martial arts training in the early 1970's and earned his first rank in a Chinese Gung Fu style. His family moved around a lot in those early years and during that time he was exposed to kenpo karate, two variants of Tae Kwon Do, Kyokushin-kai Karate, Choy Li Fut Kung Fu and an unusual Vietnamese style brought to the US by a "boat person" and former Vietnamese Ranger. Over time he became a 5th degree in Shorin-Ryu Karate with cross training in Aiki-Jutsu and weapons. It was during these years that he also honed his skills in western boxing, Arnis-de-Mano and Escrima. He started training at the Southern Methodist University Kenpo-Jujutsu black belt club which is where he first met Michael Park and they became training partners in a very arduous practice of a Motobu-Ryu based system of Kenpo-Jujutsu. After returning to Dallas from an extended stay in Europe Dr. Steiner continued intensive training in Kajukenbo and Kenpo Karate with Michael Park at his school in Plano, Texas. Chief Steiner's fitness level, education and martial art skills make him an ideal senior to senior to represent the Kajukenpo Kenpo-Jujutsu Association as a red/silver belt and next in line successor.

1Daniel Wade Park is the blood line family member who is the designated successor to the Park System.

He trained in traditional "old school" Kajukenbo until he left the island in 1998. He would later add Kajukenbo Kosho-Ryu Kenpo training under the supervision of GM Ortega.
