As a recent osteopathic graduate, I will pass on to you what was passed on to me, by many, many other DO anesthesiologists and residents: Avoid osteopathic anesthesiology residency minus a few exceptions.
Reasons to avoid DO anesthesiology residency training:
1)small, unstable hospitals-my best friends (and my medical school's teaching hospital) closed down 2 months after he started, and gave him a whopping two-days notice of closure.
2)Non ACGME board certification:translation:you won't be able to work anywhere you want-if that doesn't bother you, good for you. Seriously, if you rotate or interview at DO Anesthesiology programs, ask them hard questions about where they end up working later.
3)smaller hospitals-->lighter surgery loads--->less experience, less trauma, less practice for you, and also you might have to leave town, like a medical student again, and you may have to do rotations somewhere else for several months.
Exceptions: You are from a small town,you are going back to a small town and they are so desperate for help they don't care where you trained. You are so sold out on the Osteopathic philosophy that you don't care if adding DO residency training hurts the rest of your career.
PS I wrote this with a helpful spirit, and I mean no disrespect to you or DO hospitals, but I feel it is fair to know what you are getting yourself into.
Being in an allopathic training program erases most of my doubts about how I will be perceived as a physician, first and foremost, later when I am done.
