About

Billy Marrone, PT, DPT, SCS

I spent eight years at Hospital for Special Surgery in New York, treating athletes from youth sports through the professional level. There I completed my sports physical therapy residency, earned board certification as a Sports Clinical Specialist, and later served as faculty for the HSS sports residency and the HSS–Brooklyn Nets Lower Extremity Fellowship.

Today I practice at Connecticut Children's as a Level V sports physical therapist and teach sports physical therapy as adjunct faculty in Quinnipiac University's DPT program. I've published and presented nationally on return to sport after ACL and knee injury, and co-host The Sports Rehab Lab podcast. Marrone Sports Rehab is where I bring that experience directly to athletes, and where I share what I've learned through the articles on this site.

The Technology Behind the Program
CONTINUUM
Return to Sport Platform

Every return-to-sport decision in this program is criterion-based — gated by what an athlete can measurably do, not by how many weeks have passed. Continuum is the platform I use to track progress, gauge readiness across every domain, and progress athletes stage by stage back to full competition.

TPI Golf Assessments

The Titleist Performance Institute has spent two decades studying how the body functions in relation to the golf swing — and its philosophy is simple: there are infinite ways to swing a club, but one most-efficient way for you, based on what your body can physically do.

"If you don't assess, it's just a guess." The TPI movement screen evaluates your physical capabilities and connects them directly to your swing characteristics. As a TPI Medical Level 3 clinician — the highest medical certification TPI offers — with additional certifications across the Fitness, Power, and Junior tracks, I build the complete plan: treatment, training, and swing-relevant programming.

  • TPI movement screen — the Body-Swing Connection assessment
  • Swing characteristic analysis and physical correlation
  • Individualized mobility, stability, and power programming
  • Junior golfer development — age-appropriate long-term athlete pathways
  • Post-injury and post-surgical return to golf
