Fantastic program for both religious education and an advanced academic curriculum. Last few years, the school has improved and made huge steps towards becoming the hidden gem in the valley. I recommend if you are looking and school searching, it is a must to take a tour. Sports have been upgraded and have been another team-building effort to help teach our children and help them learn the importance of discipline and integrity.
