Sorry if this was answered somewhere else, but I did a search and didn't come up with clear answers. Thank You in advance for your input. 1) Do DO's make same money as a MD ? (Obviously money is not a concern here but just curious). 2) Can a DO do everything as an MD, i.e Are there any field that a DO is not 'allowed' in ? 3) Can a DO become a 'Fellow' in their field ?, if so, then are they treated the same as an MD Fellow ? 4) What about the rotations ?.. Is it the same as a MD Rotation ?, if different then how so ? 5) Is US the only country that has DO's ? Thanks so much. Greatly apprecieted.
