Being rooted in Catholic belief and tradition, Mater Dei accepts the responsibility, in partnership with parents, to foster faith and Christian values. Retreat days are an important part of this tradition. They offer students the time to reflect, pray, and discern the role that faith and commitment to its practice play in their lives.

Mr. Jim Darr of the Mater Dei Campus Ministry has announced that REAP Team from St. Louis will lead the junior and senior retreat days and the NET Team from St. Paul, Minnesota, will facilitate the retreat days for freshmen and sophomores. The classes will be divided in half with one half making its retreat on the first day and the other half of the class on the second day. Seniors girls will make their retreat on Monday, October 1, and senior boys will make their retreat on Tuesday, October 2. Sophomores Albers to Kitowski will make their retreat on Friday, October 12, and sophomores Koerkenmeier to Wuebbels will make their retreat on Tuesday, October 16. Freshmen Abert to Koopmann will make their retreat Wednesday, October 17, and freshmen Krebs to Wise will make their retreat on Thursday, October 18. On Monday, December 3, the junior girls will make their retreat and on Tuesday, December 4, the junior boys will make their retreat.
