If DO is such a big practice, how come I don't see that many DO doctors around (I live in cali).
DO's do not make up a large percentage of practicing physicians, especially on the west and east coasts. They are more prevelant in the Midwest. But, they can and do work at the same hospitals as MD's. In fact, my personal physician in California is a DO and she does a great job.
I am looking forward to become a surgeon, and would like to keep DO as a back up. But, once i do go to a DO school, isn't it going to be really hard to get into a residency program?
DO's have their own residencies that are reserved solely for DO students. In addition, DO's can get accepted to MD (allopathic) residencies as well. So, to become a surgeon you can do an osteopathic surgery residency or an allopathic surgery residency. Either way, you end up a surgeon.
I mean i was looking around at residents in certain teaching hospital schools like JHU and Yale, and they seem to have no DOs in their residency programs.
That's because JHU and Yale are allopathic programs. That's like saying I don't see many Chinese people in Uzbekistan.
