The Functional Fueling® Difference


We believe in treating the body as a whole, recognizing that every aspect of your health is interconnected. Our personalized program focuses on addressing the root causes of health issues, rather than just managing symptoms. By considering your unique bio-individuality, we create a personalized plan tailored to your specific needs.

Holistic Approach


Our team of experienced integrative/functional practitioners combine the principles of functional medicine with therapeutic nutrition. We analyze your health history, genetic factors, lifestyle, and environmental influences to create a comprehensive understanding of your health. This knowledge allows us to provide targeted guidance and support to optimize your well-being.

Integrative and Functional Medicine Expertise


We use advanced laboratory tests to identify your root causes and personalize your healing path. Testing allows us to identify the "why" behind your chronic symptoms or health condition so that you can start healing. We'll recommend and order your testing based on your unique health picture. We cover all aspects of this process for you. We'll combine the results of your tests with our thorough assessment to create a truly holistic and personalized healing plan for you.

Root Cause Testing


We firmly believe that food is medicine. Our personalized program emphasizes the power of nutrition to heal and nourish your body. We'll work closely with you to develop personalized nutrition and supplement plans that supports your healing, taking into account any individualized needs you have. We will ensure you have the resources fit to your lifestyle along the way.

Nourishment as Medicine


The right supplementation can expedite your healing and fill in gaps from dietary intake. After our assessment and lab testing, we'll design a customized medical grade supplement protocol to support your nutrition recommendations. This protocol will evolve as your body heals. Some recommendations will be for a few weeks and others for a few months. Supplements will only ever be used as needed and each person's needs will differ. By the time we're done working together, you will only be on a few for foundational long-term support.

Targeted Supplementation


Achieving optimal health extends beyond nutrition alone. Our personalized program addresses other key aspects of your lifestyle, such as sleep, stress, exercise, and environmental exposure. By optimizing these areas, we create a comprehensive framework that supports healing. We also teach you how to effortlessly integrate these practices and introduce new habits into your lifestyle without feeling like you're missing out on any fun. Our approach is designed to be just that - functional (which means adaptable and also sustainable).

Chief  Dietitian + Founder

I'm the chief dietitian and founder of FFN. I'm the mom of two crazy German Shorthair Pointer pups and a wife to a smart, heart-centered man. Outside of hormones and functional nutrition I have a true passion for natural food stores, my Greek culture, architecture and pottery.


I'm one of the functional medicine registered dietitians at FFN. I'm committed to helping individuals from a whole-person perspective. When not listening to podcasts, I love spending time with my dog, Kira, playing soccer, hiking and trying new restaurants!
