I'll address, best as I can, some of the comments in the last few posts. Yes, the traditional big four program in FP are UNM, Miami, NYC, and Baltimore. Each can take up to 4 fellows per year and collectively they probably train 25-30% of all FPs in North America. For example, in my office, 2 of the 9 of us did so. That said, there are many other great programs, with excellent staff and case variety. Off the top of my head these would include Atlanta, Dallas, Houston, San Antonio, Denver, Seattle, and Chicago.
I know very little about the UNM program, so I can't address the above concerns. I do know their volume is lower, and they don't have the crazy-high number of homicides like in many of the urban programs. UNM has a reputation of probably being the most " academic" of the big 4, since they are physically and administratively much more connected to their university than most programs. In addition to the forensic cases, they provide autopsy services to UNM hospitals. Two of my fellowship faculty came from UNM and both were excellent, and despite the lower homicide numbers out there had plenty of expertise with GSWs. I did over 300 total cases and 70 homicides during my fellowship in Baltimore, which was a heck of a lot. There are pros and cons to this kind of volume, and each candidate has to decide what will be best for their career. I kid not when I say I'm still more comfortable with GSW cases than I am with complex toxicology-related cases.
I don't know about staff turnover in NYC. I can say that in the 3 years I've been looking, I've not seen a single ad for positions there on the two main sites where North American FP jobs get posted. But LOTS of jobs in FP get filled without ever being formally advertised. It's a small community - most of us know or at least know of most of the rest of us.
