Learn More About Dr. Patterson

What is Integrative Medicine?

More Than Just Medicine —
A Whole-Person Approach to Healing.

Integrative and functional medicine is about getting to the “why” behind your symptoms. Rather than treating isolated conditions with quick fixes, we explore root causes — including hormones, gut health, lifestyle, toxicity, stress, and more — to create a plan that supports long-term healing and vitality.

Unrushed, in-depth visits with one physician

You'll work directly with Dr. Patterson who will take the necessary time with you. Each visit is designed to explore your full health story and build trust.

Customized treatment plans (not protocols)

Every care plan is built from scratch based on your unique symptoms, labs, and goals — no cookie-cutter protocols or one-size-fits-all solutions.

Emphasis on prevention, nutrition, and hormonal balance

We focus on what keeps you well — not just what treats disease. Nutrition, lifestyle, and hormonal optimization are central to your long-term vitality.

Options beyond prescriptions

Your healing toolbox includes more than medications — from in-depth diagnostics to targeted supplements, guided detox, and practical life changes that actually stick.

Patient Testimonials

You Deserve to Be Heard & Healed.

Dr. Patterson's calm demeanor, excellent listening skills, incredibly broad knowledge and willingness to think "outside of the box" make her an exceptional doctor!

Dr. Patterson is always friendly, personable and never hurries in addressing my needs.

I can’t say enough good things about Dr. Patterson. Our 1 year old son has seen her since he was born and she has always been accommodating and compassionate. She also goes the extra mile to dig further into things and is so thorough.

Dr. Patterson is an amazing doctor. She actually listens to what we have to say in regards to our children. She takes her time with them and she cares. She is not quick to medicate and tries to get to the root of an issue rather than putting a bandaid on it and moving on to the next patient.

Dr Patterson is a tremendous functional medicine doctor. Meaning, she looks at the whole person, and not just the symptoms the way that the average doctor does. I am a health coach, and I recommend her to all of my clients. I also have my whole family going to her.

Dr Patterson is amazing. I would definitely recommend her to whomever wants to change their lives.
