The mission of the St. Joseph's Prep Mothers’ Club is to promote interaction between the mothers of Prep students through spiritual, cultural, and charitable activities.
The defining goal of this organization is to extend the spirit of cooperation throughout the Prep as well as to support the community. Since its inception in 1934, the Mothers’ Club has accomplished its mission by organizing and staging a variety of special events that take place throughout the school year. Not only do the mothers in the club form life-long friendships with each other, they also create Prep memories while building stronger relationships with their sons. All Prep moms are invited to participate in any way they are able. Ongoing activities include Wednesday service, staffing the Prep Shop and events such as the Fashion Show and Homecoming.
