There's a peculiar vulnerability that comes with being both a physician and a parent.

We carry the burden of medical knowledge and awareness of what can go wrong; yet, we remain just as susceptible to life's unpredictability as any other parent. 

My story begins at home. Despite being a Yale-trained gastroenterologist, I was unprepared when my second child developed severe food allergies and eczema as an infant. Trained protocols - avoidance, topical steroids, epinephrine - managed symptoms but offered no root-cause solutions. Watching my child worsen despite following guidelines, I asked: What am I missing? That question led me to research early immune development and the emerging evidence pointing to one key factor: the developing gut microbiome.

My educational background includes a degree in English Literature and Biochemistry from Brown University. I attended medical school at the Albert Einstein College of Medicine in New York, completed my internal medicine training with a chief residency at Georgetown University in Washington, DC., and completed my gastroenterology training at Yale.

My husband, Sameer, and I are raising two beautiful children together. Living in the Blue Ridge Mountains of Virginia, we’re creating a life plan set in nature, surrounded by fresh air, clean water, healthy soil, farms, and whole foods to help build a diverse microbiome that can bring health, happiness, and vitality to our family.


The first 1000 days of life are a critical window for developing a healthy gut microbiome that will influence your child’s health for decades to come.


Studies show early gut bacteria teach the immune system to tell friend from foe. Disruptions can cause immune disregulation like my child’s.

To help, I redesigned my practice: microbiome testing, personalized nutrition, environmental assessments, and digestive programs addressing microbial imbalance. I also founded a "Clinic to Farm to Table" model linking patients to farms, gardens, and whole-food kitchens—born from my child’s needs and others’ lack of guidance.

This knowledge gap is what ultimately inspired me to write "First 1000 Days." Because while medicine slowly integrates emerging microbiome science into clinical practice, parents need guidance now.
