Are you talking women's gymnastics? Yes, the University of Minnesota has a good gymnastics team. They are ranked #22 in pre-season polls right now. I'd consider them a second-tier D1 school. They don't make it to nationals, but they do make it to regionals and are generally ranked top 25. One girl went to nationals for AA last year.
As for are they a good school to go to - it depends on your skill level and goals. If you are around a level 9 and want to compete a lot, then it's a great option. Level 9's generally have to walk on to the very top teams and don't get to compete much. What are your priorities: being part of a really good team or competing a lot and being a star or getting a full ride scholarship? That will influence the school you chose.
I'd recommend you go to one of their meets if possible.
