some DO friendly IM programs, all university based and strong:
Baystate Medical Center (Tufts Western Mass affiliate, big L1 trauma center)
U Conn
Maine Medical Center (UVM affiliate in Portland)
UMDNJ-RWJ and NJMS
MSU
Lahey Clinic (Tufts-Burlington MA)
-don't know any other specific programs, but any good IM programs that are located very near DO schools are probably more likely to take DO grades (i.e. the Philly programs (TJU, Temple, Drexel), any of the Florida schools b/c of Nova SE)
Most of the Boston programs are not all that DO-friendly from what I know; I'm also not under the impression that most of the West Coast powerhouse IM programs like UCSF, UCLA, Stanford, UCSD are particularly DO-friendly either.
good luck!
