Integrative & Functional Nutritionist · NYC + Virtual Nationwide
As a functional nutritionist in NYC, I help people who have been told their labs are “normal” while they still feel exhausted, inflamed, and unheard. I know that experience firsthand, and it is what led me from frustrated patient to functional nutritionist. Whether you are dealing with a stubborn gut issue, an autoimmune diagnosis, thyroid symptoms, or hormones that feel out of balance, my work starts with the root cause. Here is my story.
It All Started When I Was Diagnosed with Hashimoto's....
I was diagnosed with Hashimoto’s, an autoimmune thyroid condition, in middle school. At the time, I had constant gut issues and struggled to find foods that didn’t irritate my stomach. I figured it was genetic, just something I’d live with forever. In college, my Hashimoto’s and thyroid symptoms worsened, making it hard to get through my coursework or have the energy for a social life.
Then I took a nutrition class for the first time, and it changed how I saw food and its impact on gut health, thyroid function, and overall wellbeing. After small dietary tweaks, my energy, mood, and digestion all improved. That sparked a love for functional nutrition, and I began incorporating more of the principles I was learning.
But Then Everything Changed....
The deeper I went, the more profound the changes. Before, I lived with low energy, brain fog, and a quiet dissatisfaction with my health. As I kept applying what I learned, that turned around, and it became my turning point.
I immersed myself in how whole foods, targeted supplementation, and lifestyle changes heal the root of gut, autoimmune, and hormonal health concerns, inspired by how the right plan could create sustained, lasting improvement.
Now, I'm Able To Help You Feel Your Best!
The silver lining of my journey is deep empathy. Having lived the frustration of not finding answers, then discovering the power of nutrition and lifestyle change, I built a practice around getting to the root cause.
My work centers on integrative and functional nutrition for gut health, SIBO, autoimmune disease, Hashimoto's and thyroid health, and hormonal and metabolic balance. Every plan begins with a comprehensive health-history review, in-depth consultation, and a dietary and lifestyle protocol tailored to you, whether we work together in NYC or virtually nationwide.
