Titleist Performance Institute (TPI) certified care from a Doctor of Physical Therapy. We connect how your body moves to how you swing — relieving back, hip, and shoulder pain while building the mobility and power to hit it farther and play more often.
Most swing faults and golf injuries trace back to a physical limitation — a tight hip, a stiff thoracic spine, poor rotation, or a lack of stability. Using the Titleist Performance Institute screen, your Doctor of PT identifies exactly where your body is holding your swing back, then builds a plan to fix it.
Whether you’re fighting low-back pain or chasing more clubhead speed, the path is the same.
A full TPI assessment links your mobility, stability, and rotation to your swing.
We pinpoint the limitations causing pain or robbing you of distance.
A custom program restores mobility and builds rotational power, tested on force plates.
You return to the course moving better — pain-free, and hitting it farther.
Distance comes from rotational power and how efficiently you transfer force into the ground. We measure it objectively with force plates and build the strength, speed, and sequencing that add clubhead speed — the same approach we use with rotational athletes in baseball and lacrosse.
A perfect 5-star rating across nearly 300 reviews — straight from our patients.
TPI (Titleist Performance Institute) is the industry standard for connecting how a golfer’s body moves to how they swing. A TPI-certified Doctor of PT screens your mobility, stability, and rotation to find the physical limitations behind your swing faults, pain, or loss of distance — then fixes them.
Yes. Low-back pain is the most common complaint in golf, and it’s usually driven by limited hip or thoracic-spine rotation forcing the back to compensate. We treat the root cause — restoring rotation and stability — so you can play without pain instead of just managing it.
Distance comes from rotational power and ground force. We measure both objectively with force plates and build the mobility, strength, and sequencing to add clubhead speed — so the gains are real and measurable, not guesswork.
No. Plenty of golfers come to us purely for performance — more distance, better consistency, and durability for more rounds. Others come for pain. The TPI screen guides both.
