Since its inception, the institute has expanded internationally and has operated schools across the USA, including Boston, Cape Cod, Nantucket, Washington D.C., Vienna (VA), Florida, and Puerto Rico.

Breaking News
As of February 2025, it is widely recognized that we have led the global karate community in competitive excellence for years.
I am pleased to announce that Renshi David Bavaresco is now our Director of Competition, alongside his wife, Paoula Bavaresco, who will serve as Head of the Competitive Team. Both have consistently demonstrated outstanding performance in tournaments.
Traditionally, under Grandmaster DeBuc, our organization accepted students by referral and did not seek public recognition for its achievements. However, as of December 2024, upon becoming CEO of the Double Dragon Institute, I have modernized this approach.
Additionally, the company’s legal name has been updated to:
Double Dragon Goju-Ryu Karate-Do Organization, LLC
It is time to extend our expertise to the public. I am committed, with Grandmaster’s approval, to expanding access to our elite karate training. To support this vision, we are relocating our headquarters to Plantation, Florida, where we will open a dojo welcoming students of all ages.

We are excited to announce the relocation of our Headquarters Dojo from Pembroke Pines, Florida, to Plantation, Florida.
For years, the Double Dragon Institute has competed anonymously with the WKC & WKF, choosing not to seek recognition. However, we are now proud to reveal that Renshi David Bavaresco is one of our students. His numerous achievements include:
His additional titles and accomplishments have remained confidential at the request of Renshi Bavaresco and Grandmaster DeBuc. Furthermore, Renshi Bavaresco has trained under an overseas instructor who played a significant role in his development—this information may be disclosed in the future with their approval.
This announcement was officially made at the Tiger and Crane Organization’s Black Belt Only meeting in February 2025, before our esteemed Grandmasters and over fifty Black Belts.
As a proud partnering member of the World Tiger and Crane Organization, Double Dragon Goju-Ryu Karate-Do continues to uphold the highest standards in martial arts excellence.
By blending Sansei Goju-Ryu fundamentals with the teachings of my many instructors, we have created a unique and versatile style that gives our students a competitive edge. This is evident in the achievements of Renshi David Bavaresco and others who exemplify our approach.
Our students gain a strong foundation in Karate-do while learning how different styles complement each other, enhancing their power and adaptability. This training not only sharpens their martial arts skills but also positively impacts their academic and professional success. Many Double Dragon Institute students go on to lead companies and graduate at the top of their class.
At Double Dragon Karate Institute, we integrate Sansei Goju-Ryu, founded by Grandmaster Manny Saavedra, into traditional Goju-Ryu, forming Double Dragon Goju-Ryu Karate-Do. This style, also known as Double Dragon Goju-USA, is distinct from USA-Goju, founded by Supreme Grandmaster Peter Urban, the teacher of Grandmaster Saavedra.
Like the masters of old, we embrace continuous growth by training across disciplines, ensuring that Double Dragon Goju-Ryu Karate-Do remains an evolving and dynamic system.
