The story about the Evangelizing Sisters of Mary traces back to the early 70s when zealous and courageous men of great faith felt a divine calling to establish a religious Congregation dedicated to proclaiming Good News to the whole world through both word and action.
Missionary Congregation of the Evangelizing Sisters of Mary commonly known as ‘Evangelizing Sisters of Mary’ is the 1st African Missionary Congregation in Uganda. Right from its conception in 1975, the Congregation was founded as Missionary.
Our great Founders Rev. Fr. John Marengoni and Bishop Sisto Mazzoldi both of happy memory were Comboni Missionaries of the Heart of Jesus. The Congregation was founded in Amaler- Moroto Diocese in Uganda 1975. The pioneer members of Evangelizing Sisters of Mary were 14 Girls who came from Moshi Diocese in Tanzania and other 6 Girls who came from four Dioceses in Uganda; that is Arua, Gulu, Kabale and Tororo.

Our Charism
Our Charism is moved by the pierced Heart of the Crucified Jesus Christ the Good Shepherd; We are called to announce the Good News of the Risen Lord Jesus Christ to Non-Christians by carrying out Primary Evangelization through various ministries such as Catechetical instructions, planting the Church where it is not yet planted and bring its full development where it is already implanted.
Our vision
Our vision is to bring the whole person to the totality of human dignity by uplifting the whole person spiritually, psychologically, socially, intellectually, morally and materially. These service are rendered through training or equipping sisters with adequate knowledge in social Work, Education, Health and Pastoral Ministries.
