Functional Medicine is a personalized, systems-oriented model that empowers patients and practitioners to achieve the highest expression of health by working in collaboration to address the underlying causes of disease.

Functional Medicine offers a powerful new operating system and clinical model for assessment, treatment, and prevention of chronic disease to replace the outdated and ineffective acute-care models carried forward from the 20th century. Functional Medicine incorporates the latest in genetic science, systems biology, and understanding of how environmental and lifestyle factors influence the emergence and progression of the disease.

Nutritionists

All nutrition appointments are available remotely, conveniently fitting into your life and your schedule no matter where you are or what you’re doing.

All of our Functional Nutritionists are trained and experienced in Functional Medicine through our clinic and the Institute for Functional Medicine.

Your nutritionist will help you uncover the root causes of your issues, using detailed histories and functional laboratory testing (often included in your package), and create a highly-tailored Functional Medicine plan just for you. Our nutrition team also has the benefit of ready access to myself and Dr. Litwin during our weekly Clinical Grand Rounds, to consult on your case should that be needed.
