Golf Performance

The Body-Swing Connection

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

About

Billy Marrone, PT, DPT, SCS

I've spent my career at the top of sports medicine — eight years at the Hospital for Special Surgery in New York, the nation's #1 orthopedic hospital, treating athletes from youth sports through the professional ranks. I completed HSS's sports residency, earned board certification as a Sports Clinical Specialist, and served as faculty for the residency program and the HSS–Brooklyn Nets Lower Extremity Fellowship.

Today I lead return-to-sport pathway development at Connecticut Children's Medical Center and teach sports physical therapy as adjunct faculty in Quinnipiac University's DPT program. Marrone Sports Rehab brings that same standard of care directly to you — no clinic queues, no divided attention, just focused one-on-one work built around your sport and your goals.
