A practicing medical doctor is a professional in the field of health-care who has successfully earned a Doctor of Medicine (MD); completed an internship or residency, as well as met all required medical and state board licensing requirements. Medical doctors work in a variety of settings and within a vast number of ever-increasing specialties. Medical doctors can choose to practice alone, with a group or within an agency or organization.
Doctors are involved with virtually every facet of career specializations; from the front lines in active military combat to a solo practice in a rural, scarcely populated town in the Midwest. Often referred to as a “physician;” a doctor is one whose career is dedicated to the preservation and improvement of the quality of human life at all stages of development and in all conditions in which it is found.
