Who We Are

who-we-are-lede-1600

We are an apostolic religious community of women founded by Fr. Thomas A. Judge, CM and Mother Mary Boniface Keasey, MSBT in 1918. Our Motherhouse is located in Philadelphia and we are currently serving in missions across the continental United States, Puerto Rico and Mexico. 

By our lives as Missionary Servants of the Most Blessed Trinity, we seek first to glorify the Triune God. Our specific mission is the preservation of the faith in those areas and among those people who are spiritually neglected and abandoned, especially the poor.

Our chief effort is to develop a missionary spirit in the laity.
