Grand Opening Early 2027 — Now Enrolling

A doctor you can actually reach — now in San Tan Valley.

Keystone Natural Family Medicine is opening our fourth Phoenix-metro clinic on N Gantzel Road — the same unhurried visits and transparent membership pricing our East Mesa, Chandler, and Phoenix families already know, now minutes from home.

You asked, we listened.

We have always loved our patients from San Tan Valley — and we are so excited to serve more families in your thriving community. For years, San Tan families have trusted Keystone with their care and made the drive to see us. Opening our doors on N Gantzel Road means the unhurried, root-cause medicine you already know is finally right where you live.

This will be our fourth clinic in the Phoenix metro, built on the same promise as East Mesa, Chandler, and Phoenix: transparent membership pricing, real time with your doctor, and a practice that answers when you call.
