Another dental student here, same class as ze Sheriff.
Location is okay. It's pretty, quiet, safe, etc. There is lots of living close to the school which cuts commute times versus a school in a high density urban zone. The downside than is you get a very homogenous, unexciting place to be. Salt Lake City has it's fun spots but being further down south just makes it that much longer of a commute for fun. Just my $0.02.
Cost is high for Roseman and to say we are thrilled with it would be a lie. That said, it's a ****ty product of the times since most other private schools are that expensive and state schools are also still expensive. Everything is just expensive. What makes Roseman unique (or worth it) is the lack of BS you have to go through and the way you're treated. The faculty here want you to be competent, proficient, good at dentistry. They also don't throw endless amounts of BS projects or material at you unlike a lot of the more traditional schools out there. Faculty are very open and treat us like regular people, colleagues. There isn't a hierarchy here. P/F, block schedule, and the class being taught in a manner which prepares you for boards (rather than shoving every useless fact down your throat) are also pluses for me.
