“Allopathic physicians receive an MD. Their responsibilities are various and relate to the maintenance of health, including both acute care and prevention. Allopathic physicians can choose to practice in a number of different specialty areas, as well as build a career in teaching or research.
After medical school, all physicians are required to complete further training. It is at this time that they will choose the clinical area which they hope to pursue in more depth. A physician may choose from a number of different specialties that will vary in terms of the number of years of post-graduate training required.
Physicians practice in a number of different settings including private practice, group practice, academics, research, HMOs, clinics, industry, military, or government.
Medical school is four years in length. Typically, the first two years concentrate on didactic learning of the basic sciences and the second two years focus on clinical training in the hospital. There is however some cross over and integration of the two across the four years. After completion of medical school physicians will generally enter residency training programs that range from 3 – 8 years.
