Kumite: After winning his first world championship at age 13, J.J. competed internationally for several years and won an average of six gold and silver medals in six U.S. national championships between 2015 and 2021 but (to his dismay) only two international bronze medals. J.J. reinvented his eating and training regimen to gain size and speed and in 2022, won one Gold (Juniors Kumite) and 3 Silver medals at the World Union Karate Federation world championships after years of innovating new kumite drills. J.J. studies business at the University of North Carolina, Charlotte, and trains at his home dojo (TBK), in South Carolina, Florida, and Illinois.
Blossoming as an observant and motivating coach and Sensei: In 2024, Sensei J.J. started teaching kumite clinics as a visiting instructor. In 2025, he started teaching private lessons online to both kata and kumite athletes, and growing the highly energetic class TBK offers to 3 to 5 year olds called Ninja Flips. During 2026, after an ACL rupture that required surgery and 9 months of PT, Sensei J.J. leaned into his teaching skills and will be serving as an AAU National Coach at the WUKF World Championships in Cluj, Romania.
