A Brooklyn Physical Therapy practice built around one idea: expert assessment leads to the most effective treatment. We'll figure out what's happening with you. The rest will follow.

Low back pain

Back pain?

A free 5-minute assessment classifies your pain pattern — McKenzie, load-management, manual therapy, or movement-based — and points you to the right care in your neighborhood. Sometimes that's us. Usually it's the best-matched PT near you, and we'll tell you exactly who.

Runner?

The Running Movement Score reads two 15-second phone videos of your run and gives you a score, your movement archetype, your injury-risk indicators, and a correction plan. Not open yet — see the page to join the waitlist.
