UW-Milwaukee is relatively a newer program, so there are still some things they are working on, but their program is based off of UW - La Crosse's (they have a consortium). They have one of the smallest class sizes you'll see at 24, which makes for a very competitive admissions process. Their admissions process focuses mostly on your academic stats & GRE scores (they want to keep their 100% pass rate since they're a newer program). I also know their program is generally focused a bit more in the area of medically underserved (urban environment) populations. Overall, it's a well respected, up and coming program that will give you a great education.
I'm a 1st year at the UW-Madison (almost 2nd year) & I was accepted to all 3 programs when I applied. I also studied at UWM, so feel free to PM me with any more questions about UWM, La Crosse or Madison!
