Welcome to St. Mary Parish in Waltham. Since 1835, Saint Mary’s has served the spiritual needs of the Catholic community and all members of the Waltham community. From her beginning, the parish has been blessed to welcome immigrants from around the world. In earlier centuries, we welcomed immigrants primarily from Europe. Today our parish is blessed to be renewed by newer immigrant communities especially from Central America and Africa. Wherever you are from, we hope that St. Mary’s can care for your spiritual needs and help you know, serve and love the God who made you and loves you.
