I am an IS resident. One major way that the school is geared toward Wisconsin is the state-wide campus. In your third and fourth year, you will have the opportunity to rotate in other WI cities, both rural (La Crosse, Green Bay, Marshfield, and others) and urban (Milwaukee). Additionally, because Madison is the capital of WI, some students take advantage of the opportunity to meet with lawmakers and lobby for policy change.
Madison is an excellent city to live in if you are interested in immersing yourself in the community. If you are looking for volunteer opportunities, UWSMPH is partnered with many community organizations, including free clinics and food pantries. There is also a ton of activities unrelated to the university; Madison is consistently ranked as one of the top cities in the country for "young people" to live. Examples include the Dane County farmer's market on the lawn of the capitol building every Saturday morning (very popular), concerts and musicals downtown at the Overture Center, miles of lakeside bike/jogging trails. There's really something to do for all crowds, whether you are artsy, athletic, out-doorsy, etc.
They are going to be starting 3rd year rotations soon, but
@Jennyfishy or
@kittykattat may have more to add.
