We are devoted and committed to winning more souls to Christ and instilling morals and values to its parishioners in accordance with the Roman Catholic church teachings.
We aspire to continually derive perpetual nourishment by the sacraments and the rich devotion tradition. The congregation encourages each disciple to actively participate in individual and communal prayer with the view of nurturing and preserving a strong faith community.
The parish has two outstations that are St. Veronica Umoja Two and St. Teresa of Calcutta Tena Church.
Assumption of Mary Umoja Catholic Parish is headed by Fr. Bernard Ndichu Mwaura as the Parish Priest with assistance from Fr. Raphael Mbugua Ngethe and Fr. Marynelson Ojijo Ongiri.
