Aberdeen Catholic School System


President’s Welcome


The Aberdeen Catholic School System invites you to explore all we have to offer.

Roncalli is excited to be able to offer a truly Catholic experience, one which is prayerful, positive, affirming, and growth oriented. We are blessed to partner with parents and guardians to educate PreK-12th grade students.

Our rich tradition of academic excellence, service to our parish families and community, and competitive co-curricular activities help to impart in our students a strong foundation of faith and knowledge. The administration are committed to being servant leaders and together with the faculty strive to "teach as Jesus taught".

Come join the Roncalli family!

In Christ's service,

Tim Weisz
President, ACSS
