Hi, I'm Sheri Matthes — Functional Medicine Practitioner, nurse of 20+ years, mom of five, and someone who has been exactly where you are.

I became a Functional Medicine Practitioner because conventional medicine failed me — and because I refused to accept that failure.

I know what it feels like to sit across from a provider, desperate for answers, and be handed a diagnosis that does not fit and a prescription you do not need. I know what it feels like to watch your child fall apart while everyone around you insists everything is fine. I have lived both — in my own body and through five children, each with their own complex root cause story that the conventional system completely missed.

My panic attacks were written off as anxiety and reflux. I had zero symptoms of reflux. It was a cop out.

My son's rage episodes, obsessive behaviors, and declining health were written off too — until we uncovered PANDAS, PANS, parasites, gut pathogens, heavy metals, mycotoxins, and more.

Another son could barely read at nine. Another struggled with aggression and nightmares after illness. My daughter becomes unrecognizable around certain foods. All of them labeled. None of them truly seen.

Until we found the roots.

I did not find functional medicine in a classroom. I found it in desperation. And what I discovered changed everything — not just for my family, but for the direction of my entire life and career.

I use advanced functional lab testing — GI-MAP, DUTCH hormone testing, heavy metals, mycotoxins, food sensitivities, and more — to find what has been missed. I create personalized protocols and walk with you through every step.

I also believe healing goes far beyond labs and supplements. The nervous system, the mindset, the limiting beliefs we carry in our bodies — these matter just as much. My work weaves together root cause medicine, nervous system support, journal rewiring, frequency and vibrational health, and the healing power of nature.

I spent years as a travel nurse immersed in the most breathtaking places this country has to offer — hiking mountains, swimming in the clearest lakes I have ever seen, walking through redwood forests that felt like fairytales, standing in the silence of abandoned towns frozen in time. Over and over I witnessed what happens when a human being returns to nature. Something shifts. Something settles. The nervous system exhales.

That knowing is woven into everything I do here. Nature is not a bonus. It is part of the medicine.

You deserve a practitioner who believes you. Who sees you. Who will not stop looking until we find the root.

That is what I am here for.
