UMKC (both law and UG) has a lot of local ties to firms in Kansas City. Tons of senior partners, hiring partners, named partners etc. went to UMKC and it seems they have sort of a soft spot for the school. Plus, it's actually in Kansas City so if you went there and are looking for a job in KC, it's easy for a firm to assume you are committed to the city (as opposed to just the midwest region in general).I know a few people who go there and love it. It seems much more laid back than some of the ultra-competitve Tier 3's. I don't know that I've ever heard anything bad about it.From what I've seen working at a top local firm, KU, MU and UMKC seem to do about equally in KC. Alumni from all three are prevalent at all of the firms.
And yes, out of the whole student body some are bound to be unhappy. Have you visited to see for yourself?
