About ATP
Get out of pain, then get stronger than you were.
One evaluation, one team, one floor in Stamford. A licensed clinician looks at you across seven systems in a single session, and the plan that comes out runs therapy, strength, throwing and mental performance from the same notes. Athletes from eighth grade to the Major Leagues.
Founder
Josh Heenan
I built ATP around one idea: evaluate the whole person before deciding what to do. The question we hear most is some version of “why hasn’t this worked yet?” The answer is usually in a system nobody looked at, so we look at all seven, then decide what matters for you. I created the 90 MPH Formula, I am ATP’s founder and president, and I still keep the evaluation system honest.
The people who evaluate you run your plan.
Therapists, coaches, a throwing coordinator, a mental performance coach and a remote coach, all working from the same plan.
