Welcome to St. Mary’s Parish

We are so happy and blessed to have you visit our website.  St. Mary’s is a parish deeply rooted in the mission of the Church, where prayer and the sacraments are at the center of what we do.  Our magnificent upper Church, dedicated in 1900, is the heart of our parish.  In the lower level of the Church you will find Mary Hall, where many parish events take place.  There you will also see the Life House, the location of our very vibrant Life Teen Youth Ministry Program, which is in it’s 20th year.  The Parish Center houses the parish offices, and is located in the brick building behind the Church.  The rectory is next to the Church.  It is the residence of the parish priests, as well as for other priests with responsibilities throughout the Archdiocese.  The priests and entire staff are here for you.
