You’re looking for a dietitian who truly listens. You want space to explain what you’ve tried, what worked, and what didn’t. You don’t want to be told what to do—you want to understand what’s happening in your body and why certain recommendations make sense.

You’re dealing with low energy, bloating, or digestive discomfort. You’re trying to eat healthy, but not seeing results. Recovery feels slower, weight is changing, and your body feels off. You might also be a parent of an active child or teen, busy getting to practices, games, or lessons, and wondering if they’re fueling properly for energy, growth, and performance. I support active adults and youth (8–18) with simple, realistic nutrition strategies to improve energy, digestion, and overall performance.

Anxious, depressed, or feeling like your energy and emotions are all over the place? Is food a source of comfort when feeling stressed, bored or overwhelmed? Maybe you are caught in a binge-restrict cycle, resulting in constant food noise and a strained relationship with food, body image, and weight. If so, you are not alone. With the right strategies that account for your unique neurophysiology, it’s possible to be in control of your mental and physical health and feel like the best version of yourself. Empowerment starts by working with your mind, not against it.

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.

Food Sensitivity Nutritionists and Dietitians
What is a food sensitivity?
A food sensitivity is a condition where an individual has difficulty digesting certain foods, leading to symptoms such as abdominal pain, bloating, diarrhea, and rashes. The exact causes of food sensitivities are not well understood, and the symptoms and triggers can vary greatly from person to person. However, some foods are more likely to cause sensitivities, including gluten, soy, eggs, dairy, and certain food additives like artificial colors and sweeteners.

What is the difference between a food sensitivity and a food allergy?
Food allergies involve an immediate immune system response to a specific food, while food sensitivities result from the digestive system reacting to certain foods. Although both can cause similar symptoms, such as rashes and abdominal pain, allergic reactions typically occur much faster than sensitivity reactions. Allergic reactions can happen as soon as the allergen is ingested, whereas food sensitivity symptoms may appear 24-48 hours after consuming the triggering food. In severe cases, allergic reactions can impair breathing and require immediate medical attention, whereas food sensitivities rarely affect the airway and usually do not need urgent care.

Can food sensitivities be cured?
Currently, there are no definitive treatments for food sensitivities. Unlike food allergies, which children can sometimes outgrow or treat with early exposure to allergens or immunotherapy, food sensitivities do not generally respond to these methods. Thus, the best way to minimize symptoms is usually to avoid the foods that trigger symptoms. In rare cases, food sensitivities may resolve on their own, but, for most people, avoiding the problematic food is the only effective long-term way to manage symptoms.

Should I get food sensitivity testing?
There is little evidence to support the efficacy of food sensitivity testing. Unlike food allergy testing, which measures the body's immune response to certain foods, there are few reliable methods to assess the digestive distress associated with food sensitivities. Individuals experiencing symptoms of food sensitivity but unable to identify the triggering foods, however, may benefit from elimination diets. These diets involve cutting out certain foods to determine which ones cause symptoms. Identifying the problematic foods allows individuals to avoid them in the future, ideally eliminating their digestive issues.
