Here is some info on Sifu Bill Schettino, that points to who may have more information. Hope it helps.
Then in 1987, Bill became exposed to the formal "martial arts" in the person of Dr. Vince Black, who taught him, among other things, the internal art of Hsing-I and the art of Kajukenbo. Living with Dr. Black at this time was Sijo Adriano Emperado, a founder of Kajukenbo and a legendary martial artist in his own right. Bill was fortunate to be able to study with both Dr. Black, one of Sijo Emperado's most senior students, and Sijo himself at the same time. In addition, one of Dr. Black's students in the Internal Arts and Chinese medicine was Tom Bisio, an accomplished martial artist known for his expertise in Arnis. It was in this environment, surrounded and encouraged by men with similar attitudes about "fighting", yet vastly different skills and experiences than his own, that Bill's "process" led him to what is now known as Estacada. It was during a conversation in 1993 with Dr. Black that it was suggested to Bill that he systemize and organize his art.
In 1994, Bill moved back to New York City and, with the support of Tom Bisio, formed and started teaching classes in Estacada. In addition, Bill teaches Estacada Kajukenbo "Emperado Method" utilizing the principles and mechanics of Estacada.
