The Sisters of the Little Company of Mary

Presence...before God, for others.

The Sisters of the Little Company of Mary bear witness to the healing presence of Jesus by physically caring for the poor, sick, suffering and dying people in our midst. We pray constantly for all suffering and dying people throughout the world. In collaboration with others, we respond to the emerging health needs of the world today.

Sisters Video Our compassionate presence serves to bring physical, emotional and spiritual healing to those suffering from illnesses and fragmented relationships. The Sisters of the Little Company of Mary, our Associates, and affiliated members are called to see and act through the lens of justice, to make visible the truth that all women and men are to share the fruits of God's graciousness in Jesus.

We are a worldwide, apostolic congregation of consecrated women in the Roman Catholic tradition following the spirit and model of Calvary. The Congregation is named for the "little company" of faithful followers who stayed with Mary, the Mother of Jesus, at the foot of the Cross throughout his suffering and death.

Mary Potter founded the Little Company of Mary in Nottingham, England in 1877 and dedicated her then-small following to the Maternal Heart of Mary. She was a frail woman with a fierce determination and unwavering faith who wrote extensively on the subject of prayer and spirituality. For the next 15 years, her "little" company grew in both numbers and reputation, serving in Italy, Australia and Ireland.

Who was it that remained faithful to Our Lord on Calvary? Was it not the little group who remained in the company of Mary at the foot of the cross?

Foundress, The Sisters of the Little Company of Mary

The Sisters in Rome had been caring for the terminally ill wife of a prominent Chicago businessman visiting there. He was so impressed with the compassionate care his wife received at the hands of the Sisters, that he offered to sponsor any Sisters that Mother Mary Potter could send to the U.S.. So, in 1893, three Little Company of Mary Sisters arrived in Chicago to begin their U.S. ministry. Their efforts laid the groundwork for today's home-based hospice care and a legacy of compassionate health care in Chicago's southwest side neighborhoods.

Mother Mary Potter continued to attract women to her congregation and their ministries continued to spread throughout the world. Though she died in 1913, her charisma and her spiritual writings live on. In 1988, Pope John Paul II declared her "Venerable" Mary Potter, opening the door to her eventual canonization.
