Are there any good private schools (kindergarten - high school) in Aurora, CO?

The best private High School in Aurora is Regis Jesuit. It's located off of Parker Road and Arapahoe Road. They are incredible in academics, athletics, and have many great programs for the kids teaching them about global responsibility. This is where Missy Franklin currently goes to school (5 medal Olympic swimmer). A bonus is that you don't have to be Catholic to go there, although it is pricey, about $6,000 per year if I remember correctly.

St. Pius X Catholic School is available for K-8 for anyone looking for a Roman Catholic school. There is also a private Islamic school for Muslims but I can't recall the name.
