The Legion of Mary is an association of lay Catholics whose primary focus is the personal sanctification of its members through prayer and apostolic work. The major activities of the Legion of Mary are the attendance at weekly meetings and the completion of two (2) hours of assigned apostolic work each week such as home visitation, evangelization of non-practicing Catholics, or ministry at the El Dorado County Jail.

Meetings are held each Wednesday morning at 9:15 am in the Saint Agnes Room.
