Welcome to Saint Benedict Center, the monastic home of the Slaves of the Immaculate Heart of Mary, a unique traditional religious Order living the spirituality of Saint Louis Marie de Montfort's "True Devotion to Mary" through Total Consecration.

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, and is open to the public.

Our apostolate of evangelization is fulfilled by printing "From the Housetops," operating Immaculate Heart of Mary School, and Montfort Retreat.
