About Functional Medicine

The Functional Medicine model is a patient-centered and science-based approach that empowers patients and practitioners to work together to address the underlying and often multifactorial cause of disease. It requires a detailed understanding of each patient’s biochemical, genetic and environmental individuality. Treatments may include prescribed combinations of medications, botanicals, supplements, therapeutic diets, detoxification programs, or stress-management techniques.
