THE OFFICIAL HALBUNA OHANA ORGANIZATION
The Kajukenbo Pacific Coast Association (KPCA) is dedicated to preserving and promoting the teachings of Great Grandmaster Joseph Serio Halbuna, a direct student of Kajukenbo co-founder Adriano Emperado. We serve as the official organization for his lineage, uniting schools and practitioners who carry on his legacy.


Great Grandmaster Joseph Serio Halbuna was a pioneering figure in West Coast Kajukenbo, known for his direct training under Adriano Emperado and his lifelong dedication to refining and teaching the art. His legacy continues to shape generations of martial artists through the KPCA and beyond.
Guided by black belts that represent the various branches under Great Grandmaster Halbuna, our Board of Directors ensures that the teachings, values, and vision of the KPCA remain strong and true to its roots.
