An emerging community of consecrated life established in Michigan, May, 2010 under the direction of the Most Reverend Bishop Joseph Cistone, DD, (Bishop of the Diocese of Saginaw: 2009 - 2018). The sisters endeavor to live and work for the fulfillment of the prayer of Jesus on the night before He suffered: "that they may be one" and "For their sake I consecrate myself, that they also may be consecrated in truth."

Through the evangelical vows of poverty, chastity and obedience, the Sisters reflect more fully this "consecration in truth" which Christ accomplished by his Death and Resurrection. Together with Mary, Mother of Divine Grace; they seek to be sharers in His death, for the sake of others, which brought forth fruits of grace to a new life.

St. Mary's convent is located in Port Sanilac, MI, where the Sisters serve local parishes in the "thumb of Michigan." Known in the area, as the "Sisters of St. Mary's", they pray their presence will inspire new hope to others, both Christian and non-christian, as they seek to share the joy of serving God and giving witness to the light and love of Christ.

The Sisters strive to renew and refresh parish life and the local community by their witness, through local outreach, parish bible and catechetical studies, promoting Adoration of the Most Blessed Sacrament, the source and summit of our Christian Faith, and a religious presence at parish and local community events.
