My experience with NMU was wonderful overall. Marquette is a beautiful and safe place to live, with a great sense of community. If you love nature and the outdoors (and can handle cold & lots of snow!), this is a great place for you. Their education program is top-notch -- all of my professors were extremely knowledgeable and incredible mentors & teachers.
As far as campus, housing, and dorm life, some facilities are a little outdated. However, many have been updated or are in the works to be updated. The food on campus is alright, but there are quite a few options around so you can usually find something you enjoy! They were also extremely willing to work with food allergies, and now offer gluten-free, vegan, and vegetarian options.
