Transformative education to navigate an ever-changing world.

The Mariner Way

Character fostered in a close-knit community. Guidance based on the individual. Education developed both inside and outside the classroom. Spirituality discovered through Catholic teachings. We work hard, play with spirit and grow together. This is the Mariner Way. 

Saint Monica Preparatory nurtures kind and accomplished students who graduate with a strong sense of self, prepared to meet the challenges of a successful life and act as responsible citizens in our world. Join us on the journey!
