Many people tell us that Guerin Catholic high school is a special and unique place. Their reasons vary: Some might comment on our excellent academics and small class size. Others might appreciate our sense of community and how our high school provides our students with individual attention and a wide range of opportunities. Still others might say that it is our Catholic faith and faith-based education that is most exceptional. These are all true, of course, but what truly makes Guerin Catholic special is the fact that we are a diocesan Catholic high school. Catholic high schools can be independent, sponsored by a religious order, or diocesan.
