Our Campus
St. Dominic’s 50-acre campus is among the largest of any Catholic high school in the St. Louis area, featuring a wide range of indoor and outdoor spaces for students to learn, pray and grow.
Located on Interstate 70 in O’Fallon, St. Dominic High School’s location is especially convenient for families living in St. Charles County and the surrounding area. This closeness to home makes it possible for students and their families to be active members of the school community, making St. Dominic not just a school, but a second home.
