Actually no. Were you just looking for a reason to throw in that clever high horse comment?
I am not disparaging DO. In fact, I looked into it seriously. But the facts speak for themselves:
1.) DO schools are significantly more expensive than a state allo school. Sounds like the OP is an exception to this because of her unique circumstances.
2.) DO residency/job options are more limited than allo docs.
3.) DO is not a ubiquitous term in the public. This has the possibility to lead to numerous career complications due to other people's ignorance.
So, like I said, it is hard to find a reason why someone would forgo a state allo school for DO school. In the end, allos and DOs do the same thing. Why pay more so you can do it in fewer places?
It appears the OP has found her reasons, however. Some of them appear to be justified, others not. She also doesn't seem to be receptive to the advice she came on here asking for. But she's a gray 23, not 22, so there's nothing to really worry about.
OP, if you really want to help the underserved, go to a school that makes the best financial sense for you. It is not noble to take on unnecessary financial debt. It is dumb. Given your situation, however, it sounds like the cheapest school very well might be OU. I would still recommend, like most everyone else on here, that you take a serious look and apply to a few other schools just to be certain and also to give the appearance of due diligence. Yours wouldn't be the first time someone got rejected from a medical school due to the false assumptions of an adcom.
