Where do you stand? Vulnerable, unaccompanied children entering the United States need our help to survive.


Welcome to St. Mary–St. Catherine of Siena Parish in Charlestown, Massachusetts, U.S.A.

To visitors of our Parish, to those who have recently moved into the area and to those comfortable and nourished here–Welcome to All. And, regardless of your status in the Church, your marital state, your ethnicity, your prior religious experience, your personal history, background or sexual orientation, please know that you are accepted and respected at Saint Mary–Saint Catherine of Siena Parish.

Our Mission

Saint Mary-Saint Catherine of Siena is an urban, Roman Catholic Parish formed in 2006 from two historic Charlestown parishes. We are an intentionally inclusive community welcoming all of the many people who make up our diverse neighborhood. Because our lives are nourished by the Eucharist, we strive to build a vibrant Parish that develops and strengthens our faith and worship. With a goal of being community-oriented in the Spirit of the Gospel, we are involved in the local and global issues of our times. We are therefore dedicated to service, action, and compassion.

Please introduce yourself to the priest and register as a member of our Parish. Please use this website to keep yourself and your family informed of events and liturgical services at the Parish. We hope you will find the rich resource of this vibrant Parish, and our website, useful to help educate, inform and inspire your growth in knowledge and the practice of your Catholic faith.
