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.
