St. Anthony School has instituted a 1:1 device to student ratio for grades Kindergarten through 8th. Students in K-1 receive an iPad and 2nd-8th use Microsoft Surface tablets. Utilizing the Office 365 suite and other integrations, students have access to state of the art technology and applications to compete in the 21st century.

School Meals

St. Anthony School has several outstanding qualities and the cafeteria is definitely one. Our kitchen staff believes in utilizing the Fresh, Frozen, Canned process of delivering the highest quality food to our students. The food that is prepared daily is coordinated for the month to meet specific goals. We are positive your student will be satiated and pleased with it.

Extra-Curricular Activities

Various clubs and activities afford students the opportunity for participation and involvement in service, leadership, and development of particular talents or interests. At St. Anthony School, we offer our Archangels the opportunity to participate in the many activities outside of the regularly scheduled school day.


Every SAS family is required as per the school/parent contract to complete volunteer hours.

By providing helping hands to assist with work that would otherwise be billable hours to the school, volunteers help us cut tuition costs. Second, our volunteers foster an important atmosphere of community and fellowship, which reinforces our commitment to focus on Christian services as a part of our faith, knowledge, service mission.
