Assumption Parish Grade School




Our Mission:  To grow in love of God and neighbor and develop each child’s potential through a Catholic, student-centered education.
Our Vision: Rooted in Faith, Growing in Grace

Our Goal: Children of faith prepared for the world.


 Our Core Values:

  1. Living the Catholic faith;
  2. Engaging and comprehensive academics;
  3. Developing the whole child; and
  4. Fostering community spirit.

Our History:  “A first-class school is the glory and crown of a parish,” was the philosophy of the clergy and parents since the establishment of Assumption Parish. Stressing God’s laws while instilling the elements of the three R’s, teachers were able to reach the minds and hearts of the charter pupils of the parochial school dedicated to Our Lady of the Assumption. This philosophy has continued into the present generation.  Read more . . .
