I just noticed on the Doctors Without Borders webpage that they DO accept DOs. I am not sure how they manage DOs in countries that don't recognize our degree, however. Here is the quote:
"Does MSF consider Doctors of Osteopathy?
Yes, as long as applicants fulfill the other minimum requirements, i.e. completion of residency and appropriate licensure."
What was interesting was that they don't accept any of the other health professionals...only MDs and DOs...no DPMs, DDSs, DMDs, RNs, PAs, nothing. I suppose that's why it's called Doctors without Borders (Médecins Sans Frontières) and not Health Professionals Without Borders.
At any rate, it does open some doors for international experiences for DOs.
