I have heard that D.O.s in some states are allowed to use M.D. after their name in order to avoid confusion. After all, a D.O. is everything an M.D. is but more. For example, Ive read a post in the past regarding a person whos family physician advertised as M.D. in the phone book, but D.O. at the office. In any case, if anyone could further elaborate on the issue, it would be appreciated. I have read many posts where people have accused D.O.s of wannabe M.D.'s . Lets grow up. Dont waste your time writing this bull**** , because it is definitely not the case. Just curious.
