As Founder and Soke of the Double Dragon Goju-Ryu Karate-Do Organization and Founder of the Double Dragon Karate Institute, its official training arm, he has established a legacy founded upon technical excellence, uncompromising standards, disciplined leadership, and the development of future generations of martial artists.
With more than fifty-three years of teaching and instructional experience beginning in 1974, Hanshi DeBuc has earned recognition for combining traditional Okinawan martial arts with modern educational methods while preserving the philosophy, etiquette, discipline, and spirit that define authentic Goju-Ryu Karate-Do. Throughout his distinguished career, he has personally instructed, examined, and promoted more than fifty Black Belts, from Shodan (1st Degree) through Kudan (10th Degree). Many of his students have become respected instructors, school owners, and organizational leaders who continue to preserve and advance the traditions of Goju-Ryu Karate throughout the United States and beyond.
In 1996, together with Hanshi Yarid, Hanshi DeBuc formally established the Double Dragon Karate Institute after decades of instruction, curriculum development, and organizational planning.

This lineage, together with decades of practical teaching experience, forms the technical and philosophical foundation of the Double Dragon Goju-Ryu Karate-Do Organization.
The Double Dragon Karate Institute was founded as far more than a conventional martial arts school. Conceived as an Academy-level Temple Dojo, it was established to cultivate discipline, honor, humility, leadership, respect, and lifelong personal development. Hanshi DeBuc has consistently emphasized that true Karate-Do extends beyond physical technique, developing character, integrity, sound judgment, and service to others.
