After almost 20 years of practice, my mission is to inspire and empower people to feel happy, healthy and beautiful.

"Doctor as Teacher" is my guiding principle, as I encourage my patients to take an active role in their own health. Effective, evidence-based and individualized treatment plans are built with each and every one of my patients in mind.

As a registered dietitian I take an anti-diet approach to support my clients. Growing up as a "picky eater", I was always told how to eat and how much to eat. As I got older, I grew an interest for food and nutrition which led me to become a registered dietitian. Now I support individuals in creating sustainable dietary changes based on their preferences, dietary restrictions and medical history. I believe that embracing cultural foods, enjoying all foods and meeting your nutrition needs can all be done in sync. I specialize in pediatrics, women's health and family nutrition.

As a registered dietitian who is also personally living with celiac disease, I understand the daily challenges that come along with managing this autoimmune condition. I get how overwhelming it can be to understand food labels, feel confident when eating out at a restaurant, navigate cross contamination, and ensure your gluten free diet is nutritionally balanced.
