If that were the case, why is it that Physicians who have already completed a residency are at a disadvantage compared to applicants who have not completed a residency? Why is it that foreign trained physicians who have already been in practice for several year in another country are less desirable than 4th year medical students? You would think that a physician would be much more desirable, but they are not. You are limited in the number of years that you receive funding in a chosen specialty. I'm not sure what specialties you are talking about, but many specialties require a prelim or transitional year and thus you could just do a DO internship and go directly into the allopathic residency (I'm sure you knew that already). Other specialties like Ortho, General Surg, etc., I'm not really sure that doing a DO transitional year would be that advantageous in such programs. How much will doing Peds, FP, IM, OB/GYN, etc. really help you in a specialty surgery residency. No one asked you to take what people said as fact, they were just offering you their opinions based on their experiences. You're right though, many people have no idea what it is like to be in Michigan. Perhaps, in Michigan it is perceived as advantageous because many allopathic residency directors there know that D.O.s have to do an osteopathic internship. Speaking for my experiences in CA, many of the residency directors know nothing about the required internship. If I were a program director (which I'm not) I would rather match a graduating medical student. Yes, initially, the one that completed a DO internship may have an edge, but it wouldn't last very long. The DO transitional years are just a glorified 4th year of medical school (that's what I've been told by those who have completed one). If anything, I think doing a prelim Surg or prelim medicine might help you more depending on what residency you are applying for. Unfortunately, there are no DO programs that are exclusively medicine or surgery. Marc did say that it was his understanding and not that this was fact. I've found his insight and opinions to be quite helpful and I think your response was rather rude (I'm sure you don't really care).
