My dad is a builder/remodeler contractor here in MN. He is great. I would trust him in a heartbeat. There was a builder here in my little town who was caught shortcutting basements, and most of them flooded. But he was caught, charged, etc. If you do your research, and get referrals, and check references, you should be fine.
Btw, here, you rarely find a house without a basement because of tornadoes. Where are you planning to build? Depending on your area, and what the vast majority of houses have, that may be more of a deciding factor. Your builder, or even just a search of new houses on realtor.com, could tell you that info.
