UPMC is a great residency program from what I can see. I interviewed at 23 places last year, all across the country. I admit, I was only at each place for a day or two, and it is hard to tell that much from such a short visit, but UPMC came out at the top of my list. Since I couples matched, I was also limited by my husband's surgical interviews as to some of the interview offers I could accept...We didn't apply to SLU, and he didn't get an interview at WU so I had to miss out on WU, for instance, so I can't be much help there.🙁
The residents here are (usually) happy and friendly (everyone has bad days now and then), as are most of the attendings. We work hard, but everyone is so pleasant, wanting to teach and to learn, that it doesn't seem so terrible. (For some perspective, my husband is a general surgery intern here and there are weeks when I work more hours that he does...on some of the surg path rotations and hemepath, we come up against the 80 hour work week. But, I wouldn't come here if you don't want to work hard from time to time.
Again, if you have specific questions about the program, e-mail one of our chief residents...they are all super friendly, or you can PM me.
