I didn't match into a DO Radiology Residency, but I interviewed at several so I'll give you my 2 cents. I did 600+ on COMLEX Level 1, A's on clerkships, and had good letters of Rec.
There was a running theme at all the places I interviewed at though......YOU HAVE TO ROTATE THERE TO TRULY BE CONSIDERED!!!! And I never did a rotation at a DO rads program.
These programs don't necessarily play by the rules in my opinion, and one even sent me a letter saying that they had chosen someone else 1 month BEFORE the DO Match.....
Botsford didn't offer me an interview...so I don't know anything about their program.....but out of the places that I interviewed, I was most impressed with two: Henry Ford BiCounty/Wyandotte and Pontiac.
Good Luck.
