Philosophy
“Hormone replacement and optimization should feel clear, efficient, and supportive — not confusing or sales-driven.”
With a background in behavioral health and pharmacy, I listen carefully, simplify the plan, and use data to guide decisions so you can feel and perform your best with the least friction. Medicine is both science and relationship; I pair clinical precision with genuine listening so patients feel seen, understood, and set up for long-term success.
Background & Training
Dr. Brennecke’s journey into naturopathic medicine began through his mother, an OB-GYN nurse deployed in Vietnam, who became disillusioned with the limits of conventional medicine. When she introduced him to naturopathic care when he was 25 years old, it completely changed the trajectory of his career.

My experience across primary care, mental health, and pharmacy helps me see the big picture of how hormones and regenerative interventions affect physical, emotional, and cognitive health—and longevity.

How I Work
Expect a calm, straightforward visit focused on your goals. We’ll review labs, dial in your plan, and move forward efficiently — no pressure, no fluff.
My role is to help you understand your options and build a program you can actually live with.
I’m known for my ability to listen deeply, process carefully, and guide patients toward solutions that make sense for their lives. Working at Full Potential allows me to use the full range of my training and to practice to my full potential — which is exactly what I want for every patient, too.
Outside the Clinic
I recharge in the mountains — hiking, camping, and catching a game with my dad and my dogs.
Family time keeps me grounded and shapes the way I show up for patients: present, patient, and practical.
