As a UHS student, I will attest to the quality of our education by saying this. I have only been on rotations for two months, and I have been keeping up very well with third years from other schools who have been on rotations a few months longer than I. I have even made good impressions on some fourth years and interns, and I think my UHS education helped me to do so. So I would tell you that UHS does a very good job in training us to be doctors.
As for DMU, all I can say is that anyone I know who interviewed there has been thoroughly impressed with their visit. Personally, I have never been to the campus, but I trust the people who told me it seems like they have a great program.
As for getting "candid", I will only say this. I'm pretty sure that DMU isn't perfect, and I know for a fact that UHS isn't perfect. Every school has its faults. To me, getting accepted to medical school is an opportunity, and it is up to you to make the most of that opportunity, wherever you decide to attend. I think you will have the final say in what kind of doctor you become, not your school.
However, if all you're really looking for is "dirt" on UHS, I'm afraid you won't get that from me. Sorry.
