St. Thomas Aquinas Catholic Grade School is one of the top Catholic schools in the valley, serving students preschool through eighth grade with high academic standards. Led by principal Cynthia Scheller and pastor Fr. John Muir, the school ensures that no classroom exceeds 24 students, so every child receives the individualized Catholic education they deserve.

One of St. Thomas Aquinas Catholic School’s core believes is providing a holistic Catholic environment to serve the soul, body, and mind of each student. In a safe and vibrant academic environment, students develop intellectual and social skills to prepare them for a changing society.

Achieving high academic goals and objectives

St. Thomas Aquinas Catholic Grade School was established in 2003 by Fr. Kieran Kleczewski, V.F., and many leaders from the parish and school. Initially, the school provided Catholic education to fewer than 180 students. Today, the school serves more than 500 students in preschool through eighth grade. The school’s staff maintains high academic standards with 66% of the school staff holding a master’s degree or higher.

St. Thomas Aquinas School enables every student to gain the academic success they need to achieve the goals and objectives of the school’s curriculum in collaboration with other students and their families. The school encourages a formation in Catholic values and traditions including faith and moral perspectives, personal responsibility, and academic development.
