Established in 1960 through the efforts of a small, highly dedicated group of people, Most Precious Blood Parish is the home of the Catholic community in Dover, Massachusetts. Father John Grimes became the seventh pastor in July  2001. In 2010 the collaborative mission of Most Precious Blood Parish  and Saint Theresa of Lisieux Parish  began when Father Grimes was named pastor of both parishes. The new collaborative began sharing not only the pastor, but staff and programs as well to better serve both parishes. Upon Father Grimes' retirement in 2020, the collaborative welcomed Father Robert J. Blaney as its new pastor.

Saint Theresa of Lisieux Parish, home to the Catholic community in Sherborn, Massachusetts was established as the Saint Theresa Mission in 1924 to serve the Catholic families of Sherborn. The mission became Saint Theresa of Lisieux Parish in 1945, and now serves about 380 families from Sherborn and the surrounding communities of Natick, Ashland, Holliston, Medfield and Millis. The original church, the former town “almshouse,” was replaced by the Church - Parish Center - Rectory complex in 1993. In 2010 Father John Grimes, pastor of Most Precious Blood in neighboring Dover, was named pastor of Saint Theresa of Lisieux Parish and began the collaborative mission of the two parishes. In 2020 the collaborative welcomed Father Robert J. Blaney as its new pastor. Besides sharing a pastor, the two parishes share staff and programs, and together serve the Catholic communities of Sherborn and Dover.
