St. Justin Martyr School has been providing Catholic education from Kindergarten through 8th grade since 1966.
St. Justin is a dynamic mixture of the most effective teaching methods of the past plus new approaches on the leading edge of progressive educational techniques.
The Faith Community of St. Justin Martyr Parish supports the work of parents in fostering a faith- based Catholic education.
We strive to prepare students spiritually to be active members of our Catholic faith, heritage and traditions; academically to be cognitive, well-rounded, life-long learners; and morally to live out our Baptismal commitment to love God and neighbor, respect each other, and carry the Good News through service to all.
