Meet the Stark Strong Team

Lifelong Team

While Stark Strong Performance understands that training and conditioning are important, it is imperative that the athletes trained under us develop their characters into confident and socially empowered individuals of next-level potential. Leading by example, every athlete can benefit from a mentor, a cheerleader, and a disciplinarian to prepare them for the competitive behaviors life will challenge them with. This is why Stark Strong Performance is stellar at what we do.

Our Mission

To provide dedicated athletes quality speed development and injury prevention training; ultimately to systemize a method built on education and purpose that will reap the highest results and translate beyond our athlete’s time with us.
