Yep, being in Detroit can actually prove to be an advantage rather than a disadvantage in this situation. You will definitely not have trouble finding patients if you go to UDM. And honestly what is wrong with it being in Detroit? Yes there are some parts of the city that should be avoided but where the campus is located specifically is not one of them. There are plenty of housing facilities, restaurants, malls, etc. in Southeastern Michigan within a 15-20 drive of the campus. So if you actually feel unsafe about the city you have plenty of alternatives for when you are off campus.
On the other hand, the weather could be a problem. Michigan winters are terrible and last pretty much from November to April. In January a wind chill of -20 F was normal. Even right now in April we are still getting chilly weather (30s-40s) and spring is yet to come. Our summers are nice, but short. Idk where you're from but if you like sun/warm weather maybe it's a better idea to go to school in LA.
Oh one more thing, if you went to UDM you would definitely need your own car--public transportation is virtually nonexistent in Michigan. I don't think the same thing can be said about LA.
