maggie-thibodeau-ndMaggie Thibodeau, ND

Maggie holds an undergraduate degree in psychology from the University of Western Ontario (Ontario, Canada). After completing premedical requirements at North Carolina State University she completed a 4 year program at the Canadian College of Naturopathic Medicine in Toronto from which she graduated as a Doctor of Naturopathic Medicine.
Naturopathic medicine is a distinct health care system that blends modern scientific knowledge with traditional and natural forms of medicine. It is the art and science of disease management and prevention using natural and alternative therapies.

A Naturopathic Doctor views the individual as an integral whole, made up of physiological, structural, psychological, social, and spiritual aspects, and influenced by environmental and lifestyle factors. Symptoms of disease are seen as warning signals of improper functioning in one or more of these areas.
The primary goal is to address the underlying cause of the disease rather than solely treating or suppressing the symptoms. This approach has proven successful in treating both chronic and acute conditions.

She is also a trained Bowen Therapist and has completed additional training in managing thyroid conditions, gastrointestinal health, women’s health, cardiovascular health, environmental medicine and detoxification.
She holds professional memberships with the American Association of Naturopathic Physicians, The North Carolina Integrative Medical Society, the North Carolina Association of Naturopathic Physicians and The American Bowen Academy.
