My Story

How I found this medicine.

After college, I discovered yoga in New York City — and it changed everything. For the first time, I understood that my body wasn't something to push through or ignore, but something to care for. That realization — that health was the key to unlocking the rest of my life — set me on a completely new path.

That passion led me to medical school at Columbia, to training in functional medicine, and ultimately to founding Parsley Health — because I wanted to make root-cause, whole-person medicine accessible to everyone, not just the few.

My own healing journey made it personal. In medical school I developed severe cystic acne. I tried everything conventional medicine offered — rounds of antibiotics, birth control, Spironolactone, visit after visit to dermatologists, even cortisone injections that left scars. Nothing worked. Then I took a functional medicine approach and cut the foods most commonly linked to inflammation — wheat and dairy. Within weeks, my skin cleared, and I never needed acne medication again. It was a wake-up call: treating the root cause, not just the symptom, is the real answer. That's the medicine I've built my career around.
