Dr. Mercola is an osteopathic physician, also known as a DO. DOs are licensed physicians who, similar to MDs, can prescribe medication and perform surgery in all 50 states. DOs and MDs have similar training, requiring four years of study in the basic clinical sciences and the successful completion of licensing exams. However, DOs bring something extra to the practice of medicine. Osteopathic physicians practice a “whole person” approach, treating the entire person rather than just symptoms. They help patients develop attitudes and lifestyles that don’t just fight illness but help prevent it, too.
Also, board-certified in family medicine, Dr. Mercola served as the chairman of the family medicine department at St. Alexius Medical Center for five years. He is trained in both traditional and natural medicine.
