I don’t know anything about pre-Med, but I went to Central College in Iowa, it recently reduced tuition and is a good school and Christian based. Beautiful Dutch town. Dordt University and Northwestern College also very good and very Christian. (These are also Dutch Reformed.) DD’s BF is at Dordt and growing in his faith.
Concordia in MN or NE are Lutheran. We looked at Concordia Seward for the girls and I would have loved for them to be in that environment if other factors had worked out.
DD’19 is at a regional public but in a Bible Study, goes to Church, does line dancing with the Catholics, and sampled a couple other Christian groups, so there are options no matter where you go.
