I really liked this program! I interviewed there this past cycle as well, and all of the residents are very happy with their training and life in Denver (and I certainly can't blame them). Definitely agree with everything GABAergic said; also heard the categorical intern year is a beast and to avoid it, if possible. There's a cush TY program in town, and a decent IM prelim that a lot of residents do, which seemed like better options (didn't interview at either, though). It was in my group of "I'd be happy to see this in my envelope" programs, but I put a couple programs ahead of it based mostly on gut feeling and some subtleties on my interview days elsewhere. From what I recall hearing at the pre-interview dinner, their critical care rotations are currently pretty rough, but are being changed; residents seemed cautiously optimistic. Don't remember much about fellowship, except they send a lot to peds at Denver children's. Hope that helps!
