Hi MinnieRx. I've recently been accepted to UFs MPH in Health Mgmt & Policy, although I still have to interview with them for the MHA which is my #1 choice.
I've visited, and the school is top notch and Epidemiology has like 6 major professors I think. I met one of them (can't remember her name) while I was there; she's REALLY NICE but you can tell SHE'S SERIOUS, She's really young and recently graduated from Yale I think. If I were you personally I'd email each professor in the department with a specific question, if each can find the time to answer your question, they might be worth a shot.
I see you're conflicted with USF or UF; although USF is ranked top 20, those rankings were put out in 2007 and only included accredited colleges of public health at the time. UF would probably now be on the list. You'd have to double check USF because when I inquired about some of their programs, I was told you'd take one class on campus and all the rest online each semester (didn't like that too much). And besides don't get too caught up in the rankings...employers/professional programs won't care about rankings...they'll look at the school you graduated from and have a preconcieved perception about that program; and besides UF is much older so their connections are probably more wide spread.
Also, if you're interested in doing a professional program eventually, you should just go ahead and apply to the Dual Program options they have at UF. You can do an MPH with almost any professional degree offered on the campus (i.e. PharmD/MPH, JD/MPH, MD/MPH, PhD/MPH etc.)
Hope I've been a help. Holla.
