Our Story

The Sister Servants of the Blessed Sacrament were founded in 1904 by Silviano Carrillo, a parish priest, in Jalisco, Mexico. Father Silviano was an untiring pastor, a sower of peace and justice, and a defender of workers, Indians, and farmers for whom he established schools and apprenticeships.

On July 18, 1901, a thief stole a ciborium with consecrated hosts from the tabernacle of the parish. This sacrilege was particularly painful. It was the definitive moment when the Holy Spirit called him to be the founder of the Sister Servants of the Blessed Sacrament. His order would dedicate itself to the adoration of Jesus in the Blessed Sacrament and the Catholic education of children and young people.

His great love and fidelity to the Church led him to establish Catholic newspapers and to defend the rights of the Church during a time when priests suffered persecution by the government.

In 1921, Father Silviano was named fifth Bishop of Sinaloa. As bishop, he began a program of Christian renewal whose source was the Eucharist. He reopened the seminary. His pastoral work lasted only six months, he died in Culiacan, Sinaloa, on September 10, 1921.

Fr. Silviano Carrillo and the founding Sisters


The Province of the Immaculate Conception–the order’s first province outside of Mexico–was established as a canonical entity in 2006 with provincial headquarters in Bonita, California. The Sisters have been serving in Catholic education since 1927. They have dedicated their lives to serving the under-served populations of immigrants and children in California. The province membership is currently 46 sisters. The Sisters have ministered as principals and teachers in Catholic schools in the Dioceses of Sacramento, Fresno, San Diego, San Bernardino, and the Archdiocese of Los Angeles. The order has just celebrated 116 years of service and is currently present in 69 Catholic schools in fifteen (15) states in Mexico, two (2) schools in Guatemala, one in Chile, a large mission in Peru, and six (6) schools in the United States where over 200,000 students have attended for almost 100 years.


Where we Serve

The challenge continues today. Now more than ever, the Sister Servants of the Blessed Sacrament continue to prepare students to know and love Jesus in the Eucharist, to live the gospel values and to help build a better world for all.
