The Bridge Between
Rehab and Performance

I spent years watching the same pattern: clients would finish physical therapy, get cleared to return to training, and immediately re-injure themselves. The gap between "rehabbed" and "strong" was enormous — and nobody was bridging it.

That's why I built PTFit. I combine clinical physical therapy knowledge with evidence-based strength programming to help people train hard, train smart, and stay in the game for decades.

My Story

From D1 Athlete to Doctor of Physical Therapy

My journey into coaching started on the tennis court. As a Division I athlete at UCSD, I experienced firsthand how frustrating it is to deal with injuries that sideline your progress. I watched teammates go through the revolving door of injury, rehab, re-injury — and I knew there had to be a better way.

That experience led me to study bioengineering, where I developed a deep understanding of how the human body responds to mechanical stress at the tissue level. From there, I pursued my Doctorate in Physical Therapy, where I learned to assess, diagnose, and treat movement dysfunction.

But I realized something during my clinical rotations: traditional physical therapy often stops too soon. Patients are discharged when they can walk without pain or do a bodyweight squat — but they're nowhere near ready to handle the demands of serious training. That gap is where most re-injuries happen.

PTFit exists to close that gap. I combine the clinical rigor of a Doctor of Physical Therapy with the programming expertise of an evidence-based strength coach. The result: clients who train harder, progress faster, and stay healthy for the long haul.
