Grandmaster Milton DeBuc 9th Dan Newly Promoted in June 2025
Grandmaster Milton DeBuc 9th Dan
Grandmaster DeBuc was instrumental in creating the Temple Dojo in Sunrise and will now probably be on his way to other things. We do not know of him ever being defeated in battle, and 90% of his fights have been real-world. We were hoping he would remain with us after creating the Temple Dojo and receiving his 9th Dan, but it appears pressing circumstances have taken him in another direction; we wish him well.

Additionally, the organization’s legal name has been updated to:

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.

The same precision, discipline, leadership, operational excellence, and risk management demanded in aviation have become defining characteristics of his martial arts instruction and organizational leadership, earning him respect in both professions.
Throughout his career, Hanshi DeBuc has remained dedicated to preserving the traditions of Okinawan Goju-Ryu while adapting instructional methods to meet the needs of modern students without compromising the integrity or authenticity of the art. His leadership has positively influenced thousands of students, instructors, families, and martial arts professionals during more than five decades of continuous service.
Today, Hanshi Arthur DeBuc continues to serve as Soke of the Double Dragon Goju-Ryu Karate-Do Organization, providing strategic leadership, technical oversight, instructor certification, curriculum development, and organizational direction. His enduring mission is to preserve the authentic traditions of Goju-Ryu Karate-Do while preparing future generations of instructors to carry forward a legacy founded upon honor, discipline, humility, perseverance, integrity, and excellence.
Hanshi Arthur DeBuc's legacy is measured not merely by rank, titles, or awards, but by the generations of martial artists whose lives have been transformed through his unwavering commitment to the principles of Karate-Do.
