I did not apply to any osteopathic schools, but I have a lot of respect for people who apply because they want to learn osteopathy and land in an osteopathic practice. There are some great schools and residencies out there. I realize though that there are a lot of space fillers in osteopathic colleges, graduating physicians that serve as subsitute primary care doctors, lower in calories and preservatives than their allonothing peers.
If I struck out in this admissions cycle and had to reappy, would I appy DO? Probably not because I want to keep some options open (some avenues in contemporary medicine clash with the philosophies of osteopathy, and then osteopathy clashes with the philosophies of some residency directors).
If you come from a family of osteopaths, if you come from a state where the thing to do is become an osteopath, or if you want to practice traditional osteopathic medicine, emergency medicine, or something that doesn't make you look like you stole a seat in med school away from someone with a greater appreciation for osteopathy, then rock on.
