"The mission of Antonian College Preparatory High School is to inspire and empower young men and women to thrive while leading meaningful lives rooted in the teachings of Jesus Christ."



Here at Antonian, we view our community as an extension of family. For over 50 years, Antonian College Preparatory High School has helped shape a community of leaders who continue to engage in their communities long after they have left our school. 


Why choose Antonian? Students become prepared in a co-educational environment through a rigorous academic program that demands high expectations. Our environment places male and female students side by side, in a real-world setting, where they share in their learning and faith, become motivated to excel in all aspects of life, and become lifelong friends. Our students learn proper roles as young men and women, the modesty of personhood, and collaborate as colleagues rather than only as members of the opposite gender. This can only happen in a co-educational environment and this is what defines our school.
