Jeff Tai
Lead Coach
Jeff Tai has been coaching ninja since 2018, helping numerous competitors qualify for world finals in leagues such as UNAA, WNL, and FINA.
Before diving into the ninja world, Jeff served as the Director of Sports Performance at Jackson Strength, where he guided over 300 San Diego high school athletes to commit to D1 collegiate teams. Drawing from his extensive background in building resilient, high-performing athletes, Jeff applies a scientific, results-oriented approach to training ninja competitors of all ages and skill levels.
Outside of coaching, Jeff continually refines his techniques by testing new training methods on himself before introducing them to his clients. As one of the oldest professional ninja competitors, he aims to stay in the pro division well into his 50s. His passion for coaching goes beyond physical skills—he loves helping kids develop the mental resilience they can carry into everyday life. In his free time, Jeff enjoys playing basketball, cooking, and staying updated on the latest in sports science and training methods.
