A functional medicine nutrition approach seeks to identify & resolve the root cause.
With a specialty in nutrition assessment, I use a combination of individually tailored testing methods to establish your personal nutrition baseline and balance your body chemistry. This insures that whatever is recommended in your case is the best fit, not only for feeling better sooner, but for overall, long term balance.

I'm a Registered Dietitian Nutritionist and trained Functional Dietitian focusing on holistic approaches to healing chronic and complex diseases.
My approach to working with clients who have multiple complex conditions is to start slow. This helps prevent feeling overwhelmed and optimizes success without compromising your relationship with food. Small, impactful approaches to improving nutrition and lifestyle help to grow confidence and build sustainable habits that improve long-term health.

My approach combines functional nutrition, mindfulness and intuitive eating so that you can optimize your health without feeling restricted or stressed about food.
Together we will get to the root of your symptoms using a whole body, personalized approach. You'll have to option to use functional lab testing and access supplement protocols if needed, but I also emphasize the importance of the foundations (nourishment, sleep, stress management) with each client even when more advanced interventions are needed.

As an Integrative and Functional Medicine provider, I work with your doctor to clear up confusion, sort through health diagnoses and get you back to feeling 100%.
"One cannot think well, love well, sleep well, if one has not dined well." -Virginia Woolf. Food is an integral part of our lives and has the power to transform our mood, appearance and self worth. I work with my clients on their relationship with food to achieve the best version of themselves through balanced nutrition. I use a personalized approach to address specific nutritional needs that truly result in success. My ideal client may be confused about nutrition, struggle with not knowing what to eat to heal their body, experience weight instability or obsess over food choices.

I am a licensed nutritionist with an evidence-based approach to nutrition that marries core principles of Functional Medicine/Nutrition with the Health at Every Size and Intuitive Eating frameworks.
I love working with clients who are looking ditch diet culture, to redefine what "health" means to them, and to improve their relationship to food and body. But sometimes, the journey toward body acceptance and intuitive eating is complicated. Complex medical issues like autoimmune conditions, food allergies/intolerances, and disordered eating patterns can disrupt the relationship we have to our bodies. Most of my clients are sitting at this intersection, ready to explore a new framework and rebuild trust in their bodies.

I use functional nutrition, hormone mapping, and microbiome science to find what’s driving your symptoms so you can feel better, lose weight, and finally see real, lasting results.
I help stabilize blood sugar, reduce insulin resistance, improve liver markers, restore cycles in PCOS, support sustainable weight loss, and increase energy. Clients see measurable changes in labs and daily symptoms. I’m not a traditional dietitian. I create a personalized metabolic roadmap based on your unique patterns, not generic advice.
