i did a Physicians Executive MBA 4 yrs after finishing residency through Auburn University. It was mostly online, but they did bring us down to campus for 5 sessions (each lasting 4 days), as well as a trip to D.C. For a health policy session and to Europe for a comparative health system trip. The in person component allowed for networking and bonding with classmates like you get in a traditional MBA program, but without having to quit your job or relocate. We were a tight knit group, and I still stay in touch with several of my classmates. No GMAT or business background was required. All classmates are physicians.
There are several other name schools with similar programs - Tennessee, USC, Indiana come to mind. The degree does not carry nearly as much weight as a traditional MBA from a top program. The focus is on healthcare, and it was light on quantitative stuff (finance, logistics). It won't really open doors that wide for a total career change, but it will open doors for healthcare related business side jobs (Hospital CMO, ED medical director, CMG regional director, insurance company jobs, etc.).
Overall, I'm glad I did it. It was eye opening, I learned a lot, met a lot of great people, and no one can ever take it away from me. It's just important to realize that you're not going to all of a sudden become a great candidate for some high finance or consulting job just because you have it.
