About Dustin
Hi, I’m Dustin, founder of Peak Functional Health. I’m a Functional Nutrition Counselor, but before I ever studied nutrition, I was a patient — frustrated, exhausted, and looking for answers that sent me on what felt like a wild goose chase.

Why Peak exists
For years, I dealt with chronic symptoms that didn’t seem “serious” enough for a diagnosis, but were disruptive enough to affect my daily life. Every time I brought my concerns to my medical team consisting of several physicians and specialists, I left with less than ideal labs, a vague suggestion to “just keep an eye on it,” and some assurance that there would be medication to help me once my symptoms fully developed. The medical approach didn’t enable me to work toward health, just manage symptoms of disease.
Eventually, I decided to stop searching for quick fixes and start asking better questions. I immersed myself in research, experimented with my diet and lifestyle, and tracked how my body responded. What I discovered changed everything. When I began to remove foods that were inflammatory for me, focus on nutrient density, support my gut, and target stress, I started to feel like myself again for the first time in years.
A note from Dustin
Dustin Barrington · Founder
Certified Functional Nutrition Counselor
That experience led me to pursue formal training in Functional Nutrition. I wanted to understand how the systems of the body connect: how digestion affects mood, how blood sugar impacts energy and hormones, how inflammation can show up anywhere and everywhere. Most of all, I wanted to help others find the root cause of their symptoms instead of just managing them.
At Peak Functional Health, I help individuals connect the dots between what they eat, how they live, and how they feel. Using the Functional Nutrition model, we look beyond the surface to find the “why” behind your symptoms. This is not one-size-fits-all health advice. It’s a personalized, root-cause approach that honors your story, your biology, and your goals.
If you’ve ever felt like something was off but couldn’t get clear answers, you’re not alone and you’re not imagining it. I’ve been there. And I’d be honored to help you navigate your way toward healing.
What we believe
Every plan we build rests on three ideas that shape how we see your health.
You are unique.
Your symptoms, history, genes and experiences are yours alone. You need an individualized approach that honors your story, not a one-size-fits-all protocol.
Everything is connected.
Your body isn’t a set of isolated parts. Digestion, hormones, brain health — all of it is linked. We look at the whole picture to find the true roots of dysfunction.
All things matter.
Food, sleep, stress, movement, relationships, environment — all of it plays a role. We help you focus on the most impactful shifts, step by step.
