To Jesus through Mary! Welcome to the monastery of the Slaves of the Immaculate Heart of Mary, two separate communities of Brothers and Sisters living traditional religious lives in the spirituality of Saint Louis Marie de Montfort's "True Devotion to Mary." We are faithful to the Holy Father, Pope Francis, and loyal to the Latin Tridentine Mass which is offered daily here in Immaculate Heart of Mary Chapel.

The monastery complex of Saint Benedict Center is in Still River, Massachusetts.
