About Zac

Zachary Rhyner, PT, DPT, founded Grindstone Performance Physical Therapy with a simple belief: your care should be guided by your goals, not by insurance restrictions, productivity quotas, or one size fits all treatment plans.

As a Duke University–trained Doctor of Physical Therapy and retired Air Force Special Tactics operator, Zac specializes in helping active adults and athletes overcome pain, rebuild strength, and confidently return to work, sport, and the activities they enjoy. Every plan of care is tailored to your individual goals and uses the treatments and strategies that best support your recovery, helping you build lasting resilience instead of simply providing temporary relief.

##The Grindstone Difference At Grindstone Performance Physical Therapy, every session is one-on-one and every recommendation is based on your goals, your examination findings, and the best available evidence.

We believe rehabilitation should help you return to the activities that matter most—not simply reduce pain. Whether your goal is lifting heavier, running farther, competing at a higher level, or keeping up with your family, your plan of care is built around what you need to get there.

Transparent, all-inclusive pricing. Your treatment includes the interventions that are appropriate for your condition, without surprise charges or add-on fees. Services such as dry needling, blood flow restriction, manual therapy, movement analysis, instrument-assisted soft tissue mobilization, and therapeutic exercise are incorporated when clinically appropriate.
