Mary Ann Sammon, responding to the plight of orphaned children in the late 1800s, founded our congregation to promote the welfare of destitute, homeless, and unprotected children.


We take our founding mission seriously, and through our works of charity and our struggle to understand the causes of injustice, we work to create systemic change.

Our Work as Promoters of Peace and Justice


Our Sisters and Associates have continually responded to the sign of the times through social justice work.


Following the mission of Jesus, we yearn for a more just world and strive to recognize and challenge the unjust structures of our day. 


Our work for systemic change is empowered by our collaborative efforts with the larger Dominican Family. 


We have partnered in advocacy with two organizations: one national—North American Dominican Promoters for Justice, Peace, and Care of Creation—and one local—OPSCC (Dominican Sisters in Committed Collaboration), with the Amityville, Blauvelt, Caldwell, Hope, Maryknoll, and Sparkill congregations.
