Welcome to Mary, Undoer of Knots Parish, formerly St. Robert Bellarmine – St. Constance Parish!

Are you new to the parish? Please download the New Parishioner Registration Packet and return it the rectory office. We hold new parishioner dinners several times throughout the year to give you a chance to meet others and learn more about the parish community. Once you register you will be invited to the next gathering. Hope to see you there!

If you have any questions, Barbara Donnelly in the rectory office would be happy to help you.
