Character, compassion, and values- these three attributes are the focus of Catholic Schools nationwide this school year.

Jesus teaches us that to be a person of character, we must live our everyday lives as He did through good works and gentle words to others.

We work for Jesus every time we answer the human cry for acceptance, tolerance and love with compassion.

We value the lives of others because we know that all people are made in the image and likeness of God.

Teachers and students strive to treat every individual with the same care that we would treat Jesus.
