I'll add my two cents...first, a little background: I actually did a year of emergency medicine there before switching over to internal medicine (for reasons that had nothing to do with my satisfaction with the program, I just found that I loved internal medicine and to the faculty's credit, they supported me through the switch).
When I was at OUDEM, the program was still relatively new (about 2 years old), but I was very happy with the faculty. In fact, I would probably call it the greatest strength of the program. The chair, Stephen Thomas, is fantastic. He's very supportive of the residents, expects a lot, but I think he'll be able to take the program where it needs to go. He will take the time to get to know each of the residents. The program director, Bo Burns, is another one of the strengths...really bright guy, very easy to work with, can't say enough good things about him. I saw Dr. Whelan mentioned earlier, and she (along with Thomas and Burns) is one of the real strengths of the program. She's excellent with ultrasound (and this is coming from a guy that never got real interested in ultrasound) and is a fantastic teacher. The point of the above paragraph: Can't say enough good things about the faculty.
Since it's been several years since I've been there, I can't comment as well on the other aspects of the program (current residents, patient population, etc). But I think it says a lot about the character of the faculty that even when I decided I wanted to switch to a different residency, they went out of their way to accommodate me and found a IM residency that was a perfect fit. As I said above, my two cents...
