Team Underground



Founder / Owner

Justin founded Underground Athlete in 2008 with a desire to create something different. Drawing from his experience in the military (USMC), college (SUNY Brockport - Exercise Phys.), and his experience working with both athletes and general population clients, Justin set out to create a place where virtually anyone could receive expert coaching to look, feel, and move like an athlete.
