Thank you for your interest in Mater Dei School!

Mater Dei School provides an accelerated yet basic Catholic education in which character development is emphasized and appreciated as much as academic accomplishments. In a traditionally structured, yet relaxed atmosphere, the students are encouraged to both work and play hard; accordingly, a strong athletic program complements the scholastic curriculum.  


Below, please find the general school and admissions information, which you might find helpful.  Feel free to call anytime with questions.  We hope that we may be of service to you, and we look forward to your personal visit.
