+ Functional Medicine

A subspecialty of integrative medicine, Functional Medicine seeks to identify and address the root causes of disease, and views the body as one integrated system, not a collection of independent organs divided up by medical specialties. By assessing the biochemical, genetic, structural, and emotional influences on health, not just the symptoms, patients can prevent, slow down, and often reverse chronic illness.
