Essential Information. Doctors are licensed medical practitioners who have undergone 11-15 years of training to gain a license. This usually includes four years of undergraduate education followed by four years of medical school, divided into two years of classroom training in medicine and two years of clinical training.
Like all allopathic physicians (or MDs), osteopathic physicians complete 4 years of medical school and can choose to practice in any specialty of medicine. However, osteopathic physicians receive an additional 300 to 500 hours in the study of hands-on manual medicine and the body's musculoskeletal system.
