OUR VISION

Welcome to HormoneSynergy®. We know that aging isn’t optional, but optimal aging is. We also know that health and longevity are not merely the absence of disease, but the presence of optimal physical, mental, and emotional well being. HormoneSynergy® provides the most advanced treatments for slowing the effects of aging and cognitive decline, while restoring health and vitality with the use of natural therapies, supplement and lifestyle recommendations, medication if and when necessary, and bioidentical hormones.

Dr. Kathryn Retzler

Physician, Author and Educator

"I believe many people settle for a negative definition of aging. I do not accept that aging means falling apart on schedule. I have a high standard for my physical, mental and spiritual health, improving every year. I hold the same vision for my patients."
