Our School

At St. Thomas Aquinas Catholic School, it is our mission to be an inclusive Catholic learning community that inspires every student to achieve their full potential through faith and education. We recognize our call to love and serve from our Master teacher Jesus Christ, and we are committed to creating a Catholic learning community under the protection of Mother Mary.

The Catholic Graduate Expectations are our foundation as we strive for academic excellence and the acknowledgement of those who achieve it. We recognize God as the source of all life and actively work to focus on social issues within our local and global communities.

We celebrate the diversity within our community with a collaborative approach to learning, in cooperation with parents, the Catholic faith community, and other organizations that recognize the value of our mission. Within the context of Catholic teaching and Sacramental living, our school community strives to demonstrate respect and reverence for all life, thus nurturing a safe, Christian environment for the entire school community.

Patron Saint 
Our patron saint is St. Thomas Aquinas, the saint of Catholic schools, colleges and universities. As a young boy Thomas was described as talented, meditative, diligent in his studies and very devoted to prayer. He grew up to be a noble man who was most well known for his writings in philosophy and theology. Thomas was a brilliant man and had extraordinary powers of concentration, but this intellectual man was also very humble. He prayed often and acknowledged that all his gifts came from God. The feast day of St. Thomas Aquinas is celebrated on January 28.  

As Catholic educators, we live according to our Father's code and to lead our students, by example, to live the basic truths of the gospel message. This is an awesome, yet inspiring challenge which we share with the parents of our young men and women.

Children learn what they live. Each day we have the opportunity to teach our students:

  • to love by the way we love;
  • to be generous by our generosity;
  • to be passionate by our compassion; and
  • to be forgiving by the way we forgive.

However, a person cannot give what he or she does not have. Unless we are living the Gospel message, we cannot lead our students to do so.

There are many hallmarks of a Catholic educator, including:

  • Prayer - The challenges of our vocation, and indeed life in general, are great. To meet them we need to follow Christ's advice that we "ask the father in My name". Each Catholic educator has a duty to expose students to his or her particular style of prayer in order to assist students to recognize the value of prayer in daily life.
  • Eucharist - Parish, school, and staff liturgies provide opportunities to celebrate our faith. Our example can testify to the Eucharist as a joyful source of strength and community building.
  • Social Justice - This is the heart of the Christian message, that we "love one another as I have loved you". As our brother's and sister's keepers, we must be concerned about the aged, the poor, the oppressed, and any other marginalized group - both at home and abroad.
