I'm pretty familiar with the school, but less so with the baseball program. My daughter looked at NorthPark, and we visited it together. I have many friends who went there and whose kids either attend now or did recently.
My daughter did not end up there, but we liked the school. It is religiously affiliated for sure, but it is not as strict as other Christian colleges. It is quite diverse, and its setting in Chicago makes it so it is easy to take advantage of all Chicago has to offer.
I don't know anything about their baseball program, but the school is very focused on sports. They have a few DIII national championships - I think in Basketball for sure, maybe s****r. A good friend of mine is their most famous basketball alum - Mike Harper, who played NBA for the Blazers and settled in Portland.
For what it is worth, every person I know who went there is a fine person.
