Say, what does D.O. mean when it comes after the name of a doctor? Why not M.D.?

A D.O. is a doctor of osteopathic medicine. They get their degree from a osteopathic school.

An M.D. is a doctor of medicine and the degree comes from a traditional medical school.

Both are legally certified docs with similar training. The difference lies in the philosophy of medicine they are taught in school.
