Dr. Michelle Retz, N.M.D.
Gastroenterology, Mental-Emotional Health, & Hormone Specialist
My Care Philosophy
I believe psychological healing begins when you feel listened to, cared for, and heard. I strive to provide the best bedside manner with my patients, and to truly meet them where they are. I spend 90 minutes with new patients, evaluating all of the various aspects of their life that contribute to their current health picture. No two people with the same health concern receive the same treatment, which is great! This medicine is individualized and tailored to YOU.
Ultimately, my aim is to empower and educate my patients to take control of their health. I dedicate myself to patient-centered care using holistic medicine that treats the cause of illness, restores health, and preserves vitality.
