Twenty-seven years in pursuit of the upstream cause.

I'm Brie. Licensed primary care provider, trained in Traditional Chinese Medicine, Functional Medicine, and integrative endocrinology. I have spent the last twenty-seven years building a practice for the patients the system runs out of road for.

§ The practice

I started in the harder corners of medicine. Early in my career I worked in integrative oncology with Hepatitis C patients — people for whom standard treatment was brutal and outcomes uncertain. I went from there to IVF and fertility medicine at several Bay Area practices, working alongside reproductive endocrinologists. Fertility taught me something I have never forgotten: outcomes live in the details. The result and the near-miss are separated almost entirely by whether someone was paying close enough attention.

I founded an integrative clinic in Santa Cruz, California, directed it for a decade, built a clinical team, and eventually moved the practice fully into telehealth — which turned out to be the right call long before the rest of medicine caught up. My patients are now across the United States and in more countries than I can keep track of.

The clinical problem has stayed the same throughout. Most of the women I see have already been to four or five providers. Their labs are “in range.” Their symptoms are not. Somewhere along the way they were told the problem was their stress, their weight, or their age.

My job is to keep looking after everyone else has stopped.

§ The method & the work

Reverse Age Method

Functional medicine is what happens when you don't accept that explanation. It is rigorous, evidence-based, and stubbornly individual. I run the labs that tell a different story. I design protocols that change in real time as the patient does. I treat the body as a system — which means that when something is wrong in one place, I look for what is already wrong in three others.

In 2024 I built the Reverse Age Method: a clinical AI platform for women in perimenopause. I encoded twenty-seven years of clinical protocol logic into an agent that can hold what I hold — the full picture, the upstream cause, the sequence that actually works. The goal was never to replace the clinical relationship. It was to make what I know available to women I will never meet.

That work brought me somewhere I didn't expect: into the room where the future of clinical medicine is being designed. I write and speak on the ethical integration of AI into functional and integrative practice. I consult on the clinical architecture of products designed to serve patients the current system leaves behind. The clinical intelligence that comes from twenty-seven years of treating complex cases is exactly what is missing from most of what is being built — and I want to be part of fixing that.
