So, what you are saying is that if you graduate from a DO program, you should be considered equivalent to Pritzker? I'm sorry, maybe with zero experience in this area it looks like that, but where someone goes to school makes a difference.
You have a habit of twisting people's words, so let me be explicit. There is good training to be had at most MD/DO schools. But, there are fundamental differences between Caribbean graduates, other IMGs, DOs, MDs from most schools and MDs from the top schools. Every single class is a bell curve and there is a reasonable amount of overlap between them. I'm sure there are even people at the top end who would be standouts anywhere. But, do not kid yourself. There are very very good reasons why even those that get through an MD in the Caribbean or DO programs in the US don't match certain ACGME spots and it has nothing to do with biases among program directors.
He is right. Individual merits matters fare more than anything else. For 95%+ of applicants, your school matters next to nothing. For those 5% where it does impact things, it ranges quite a bit. (competitive programs/specialties). Of course, this assumes that we are talking USMDs compared to one another. Everything else is a completely different story.
