A Community of Women Religious

We are the Sisters of St. Casimir, a community of women religious founded in 1907, in Scranton, PA, by Venerable Maria Kaupas. Mother Maria desired to found a congregation which would sustain and nurture the faith life of the early Lithuanian immigrants in the United States. She encouraged her Sisters to do the same and then to “welcome” and care for all others who would become part of their lives. 

Our Patron, Saint Casimir

Our History


The birth of Casimira Kaupas

Casimira Kaupas, later Mother Maria, born in Ramygala, Lithuania, on January 6, 1880.


Mother Maria Kaupas moves to the United States

Casimira Kaupas arrived in Scranton, PA, to be a housekeeper for her brother, Rev. Anthony Kaupas, pastor of St. Joseph Parish. It was during her four – year stay that Casimira saw Sisters for the first time and witnessed the poverty and spiritual needs of the Lithuanian immigrants.


A new director and spiritual guide

Rev. Dr. Anthony Staniukynas consented to be the director and spiritual guide for the new congregation which Casimira agreed to found. Pope Pius X granted Bishop J.W. Shanahan, Bishop of Harrisburg, PA, permission to establish the Congregation in his diocese.


Founding of the Congregation

Congregation of the Sisters of St. Casimir is founded on August 29, 1907, at the Motherhouse of the Sisters, Servants of the Immaculate Heart of Mary in Scranton, PA.  The first three members professed their vows and Casimira Kaupas was named Sister Maria; Judith Dvaranauskas, Sister M. Immaculata; Antanina Unguraitis, Sister M. Concepta.

The Sisters of St. Casimir Motherhouse was built in Chicago, IL, and served as the Congregation headquarters.  It was here where almost 500 women received their formation, pronounced their vows, and were sent forth in service to God’s people.  The sacred space of the chapel deepened the spiritual life of the Sisters through prayer, Eucharist, and solitude with God. The Motherhouse remains a symbol of stability and peace in the neighborhood.
