D.O. (Doctor of Osteopathy)
Similar training to M.D., but focus on the body structure (bones, nerves and muscles) in the belief that problems with these are often the causes of illness and manipulation can be a cure. They attend specific osteopathic schools that cover much the same information as traditional medical schools, in addition to manipulative therapy, and are qualified to treat the same illnesses. Most D.O.s specialize in primary care disciplines and practice exactly like M.D.s while others concentrate on herbal and alternative remedies.
