Several of my colleagues started at UCCs, most have moved around, some have left UCC work, some have gone to the VA. I interned and postdoc'd at one and was open to staying. I enjoyed the variety of the clinical work, the students, the focus on education and training, the integrated care model (we were in the same building as the campus medical center), my colleagues, the hours, the access to university events, and the overall location. Not so great was the bureaucracy inherent in a large system, the somewhat competing interests re: image vs. reality of campus mental health, and unrealistic expectations from non-mental health campus leadership.
Pay was ~90k iirc about 8 years ago, in a high COL area. Not terrible, but still could be tough for some to make it out here on that salary.
For reference
here are current openings (type psychologist into the search bar) $104-125k
