Some of the more prestigious programs, in no particular order:
Denver
Cincinnati
Hennepin County (Minnesota)
Oregon Health Sciences
New Mexico
Cook County (Chicago)
There are many others, no doubt, but I'm just starting to research EM myself.
Malignant programs - so I'm told:
Hopkins
Yale
Yale is bad. They run you into the ground and the faculty is not no nice. Hopkins sucks, plus EM docs there are caught in a petty turf war b/t IM and G-Surg. At Hopkins, they look at EM docs as being just a notch above scrub techs and nurses.
(Please, somone flame me about how all docs should just be considered a notch above nurses, or how scrub techs do a valuable job.) 🙂
