My Story

Cancer survivor turned
root-cause practitioner.

When I was diagnosed with cancer, I was told “there is no known cause.”
So I set out to find answers.

What I learned led me down the rabbit hole of root causes — the accumulation of stressors that inhibit the body's ability to heal itself.

My root causes go as far back as I can remember. But when I was 19, my body went from subtle signs to screaming for help. I became debilitatingly weighed down by fatigue & brain fog.

Doctors said “there's nothing wrong,” “it's in your head,” “monitor energy expenditures wisely” — and that was it. There was no conversation about how to reverse my symptoms, only how to manage them.

As time passed, no matter how clean I ate or how routinely I exercised, I was never really healthy. Leaving my root causes unaddressed progressed to something that couldn't be ignored — cancer at 26.

It was at my health's rock bottom that I found what I wish I had known years earlier.
And this is what I have built my practice around.

Worked with hundreds of clients · 90% success rate

Master's in clinical & research physiology · trained through IIN, A4M & ASRM.

My Approach

Root-cause care for reversing symptoms, not just managing them.

You hold your work to a high bar. Your health deserves the same: we find what's actually driving your symptoms and reverse them in the order your body responds to.

01

Find the real driver

We look upstream from the symptom to what's causing it, and use functional testing so your plan is built on your data.

02

Heal in the right order

Order is everything. You can't pull something out of the body without first giving it a clear way to leave, or it recirculates and you feel worse. If you've tried functional medicine and stalled or felt worse, it's usually a sign things were done out of order.

03

Built for getting back to life

No list of 20-plus ongoing supplements. What I give you is concise, rotated, and aimed at one purpose at a time. Healing is short-term, not forever.

Questions

Good to know before we begin.

What's your background and training?

I'm a functional care provider trained in nutrition, cellular health, gut health, detoxification, preconception, and fertility. I hold a master's in clinical and research physiology and previously worked in hospital-based cardiac rehab before transitioning to root-cause care, with additional training from the Institute for Integrative Nutrition (IIN), the American Academy of Anti-Aging Medicine (A4M), and the American Society for Reproductive Medicine (ASRM). That transition was inspired by my own experience as a young-adult cancer survivor and my desire to study and heal the root causes of chronic symptoms and conditions.

In practice, I maintain a 90% success rate reversing biotoxin illness, autoimmune conditions, and chronic unexplained symptoms, alongside a 98% client retention rate. Through integrative medical collaboration, my clients have seen a 54% reduction in prescription medication use across complex cases.

Are you a medical doctor?

No. I'm a functional root-cause practitioner and health coach, not a physician. My work is educational and complementary to your medical care, and it doesn't replace diagnosis or treatment from a licensed provider. Many clients keep their doctor in the loop as we work together.

Who do you work with?

High performers who've been running hard and now carry chronic, ongoing symptoms they want to reverse, so they can operate at full capacity and get their energy back.

What exactly is root-cause care?

Instead of managing symptoms forever, root-cause care looks upstream to find what's actually driving them. We support the body's own systems (gut, detox pathways — kidney, liver, lymph), and nervous system, in the right order, informed by functional test results.

Do you work virtually?

Yes. I work with clients virtually, internationally, to complement demanding travel and work schedules.

How do I start working with you?

Three ways, all in the Work With Me section above: book a consultation if you're considering concierge care, start with functional testing and an interpretation call if you want answers now, or begin with a Root Cause Audit through my referral partner, Chelsea Rowe Smith.

Will you replace my supplements and testing with your own?

For the most part, yes. We'll audit what you're currently taking, and I'll be honest about what you actually need. For your healing protocols, I use functional testing to tailor your plan, and professional-grade supplements provided through my Fullscript dispensary. Protocols adjust as we go rather than following a fixed template.
