Your diet should fit your life, not the other way around. I will help you sift through the noise and guide you towards long-term success.

Years ago when I was motivated to revamp my diet, I did what we all do: I went online.  Overwhelmed by an avalanche of contradictory information around nutrition and health, I didn't know what or whom to trust.  That's why I became a Registered Dietitian Nutritionist (RDN).

Today, I want to use my evidence-based training to help you transform your conversation about food from what you "can't have" to what you should eat more often – whole, minimally-processed foods, especially plants. Why more plants?

When we sift through the noise, what remains is a large body of evidence, collected over many years, showing that people who include at least 75% plants on their plate have a decreased risk of chronic disease.  That is the foundation. What does it look like? Well, that’s the beginning of a wonderful conversation about food. There are many ways to fill a plant-focused plate - Paleo, vegetarian, flexitarian, vegan, gluten-free, or dairy-free. I am here to guide you.  Central to my approach is the belief that food is more than a calorie, a protein, a carb, or a fat. Food is nourishment, food is medicine, and let’s not forget, food is comfort.

Since 2017, I have been working one on one with my clients to support their nutrition goals around healthy eating, vegan eating patterns, weight management, Type 2 Diabetes, cardiovascular disease, PCOS, digestive issues and more. 


Working together we will explore the roles of food in your life, how to integrate these foods into your day to day through your grocery cart, your pantry, and prep and cooking strategies to build a healthy, sustainable path forward.

In 2022, I co-founded the Nourish and Thrive Nutrition Center along with my RDN colleague Elisa England. The center is home to our individual private practices, where we are busy seeing our clients for one to one nutrition counseling. The Center is also a vibrant community education space where we love hosting guest speakers and small group meetings around a wide range of health supporting topics. The RDNs of Nourish and Thrive also enjoy going out into the community and offering in-person presentations and cooking demonstrations around delicious whole foods.
