About us

Medicine built on knowing you.

A small-town internal medicine practice where your care stays personal.

The practice

Comprehensive care, close to home.

Our physicians and nurse practitioners practice side by side in one Fairhope office, sharing records, on-call coverage, and a common standard of care.

Drs. William Herron, Regina Felkner, Frank Wang, Steven Wittmer, Audrey Flower, and Kyle Clark — with Nurse Practitioners Kimberly Nolte and Mollie Dean — bring experience in caring for the whole patient, not just a list of conditions.

It is a practice built around continuity: same place, same people, and the kind of long-term context that keeps medicine personal.
