FOUNDER · DOCTOR OF PHYSICAL THERAPY

Meet Zachary Rhyner, PT, DPT

Recovery is more than something Zac has studied. He has lived through extensive orthopedic trauma, a transected sciatic nerve with paralysis below the knee, multiple surgeries, chronic pain, and every stage of rehabilitation. That experience shapes a practical approach built around adaptation, strength, progressive loading, resilience, and the confidence to move forward.

ZACHARY RHYNER, PT, DPT · FOUNDER OF GRINDSTONE PERFORMANCE PHYSICAL THERAPY

Built around what you need to do.

01

Experience that changes the conversation

Zac understands that recovery is rarely linear. He knows the frustration of losing physical capacity, the uncertainty that can accompany persistent pain, and the work required to rebuild trust in your body. That perspective helps him meet patients where they are without lowering the standard for where they can go.

02

Prepared through service

His perspective was also forged through years as an Air Force Special Warfare Combat Controller, including service within a Special Mission Unit operating at the highest level of military special operations. He brings the same preparation, adaptability, and resilience to rehabilitation.

03

Training and philosophy

Zac earned his Doctor of Physical Therapy from Duke University. His care combines clinical reasoning, current evidence, progressive strength and loading principles, and objective measurement when appropriate. The goal is not simply to help you hurt less, but to help you return prepared for work, sport, and life.
