First, let me say that UCHSC is a terrific school with a great, and growing reputation in primary care. There are alot of fantastic opportunities to work with underserved communities (not as much inner city as east coast schools, but alot of native american and hispanic populations.) Also, research opportunities are very good.
After saying all of this, I probably sound crazy saying that I didn't like it. But I really wanted to go there since it was my home state, so when it didn't measure up to my expectations, I was more disappointed than most people would be. I really did not like the staff or the faculty interviewers -- I felt they were arrogant and condescending. I had a very difficult time getting any information about the school, the application process, the interview day, etc... I went back to the "second look" day for accepted students in the spring, hoping that maybe things would be better, but they weren't. The students were okay, but I definitely was more impressed with other schools. The facilities seemed pretty mediocre, but not terrible. The beauty of Denver would make up for the ugly campus. (I didn't see the hospitals--those might be nice.) Finally, I am not planning on entering primary care, and it seemed that my opportunities might be better elsewhere.
I actually got into a few schools, and would have gone to any of them before going to CU. While I love Colorado, perpetually sunny, warm, fun California will have to do for now.
