Since 1974 the Park School of Martial Arts was first in Plano, Texas (a suburb of Dallas) and in continuous operation since then. Kajukembo Self-Defense Concepts (KSDC) was founded by Michael D. Park, 8th degree master of Kempo Jujutsu as an expression of his life-long experience in mixed martial arts and especially the "root styles" of Kajukembo to include Karate (Tang Soo Do) and traditional Jujutsu. The Park School is one of the few "kempo karate" organizations world-wide that acknowledges the influence and actively promotes traditional jujutsu aspects of our art. Master Park earned his first black belt in 1969 and was added to the Kajukenbo ohana in 1972 under native Hawaiian grandmaster James K. Roberts Sr. Today he is under the direct supervision of AKA founder grandmaster Alii Don Nahoolewa. The Park School of Martial Arts supports an adult only membership with ages from 18 to 63. The school offers traditional (old school) and innovative new instruction in the original hard style or "kempo karate" as founded in 1947 by Sijo Adriano D. Emperado. This knowledge has been preserved and passed down through the prestigious lineage of great grandmaster Aleju Reyes Sr, to our senior grandmaster Alii Don Nahoolewa.
