Complex illness demands a new and different medical model.
Root Causes Medicine is a functional medicine practice devoted to evaluating patients as a whole person and searching for the unique causes that are contributing to illness. Our providers dig deep into the underlying and often hidden causes of illness and use natural methods whenever possible to relieve symptoms and reverse the progression of disease. The Functional Medicine method provides a new way for medical providers to consider complex problems and provides a new way for patients to manage their illness.
Root Causes Medicine doesn’t treat medical conditions. We treat People.
