Dr. Marcus Elliott, M.D.
Founder and Director
Founded in 2006, P3 is the first performance facility to use advanced sports science technology — 3D motion capture, dual force plates, and proprietary biomechanical analysis — to assess and train professional athletes. What started as a vision by Harvard-trained physician Dr. Marcus Elliott has become the gold standard in data-driven athlete development.
P3's database of athlete performance and kinematic data is the most comprehensive in professional sports. Before the 2018 NBA Draft, Dr. Elliott's biomechanical analysis identified Luka Dončić as a generational talent — insights that, as the Wall Street Journal reported, eluded all 30 NBA franchises. Their ability to predict knee injuries with 75% accuracy based on biomechanical assessment alone has fundamentally changed how teams evaluate and protect their most valuable assets.
