RANCHO CUCAMONGA—On September 13, 1965, with the help of Father Frances Horvath, the Sisters of St. Francis of Christ the King opened Anton Martin Slomsleck School in honor of the saintly bishop.
The sisters were dedicated to spreading the gospel message and with just 58 students, began teaching children in the area. In 1966 the enrollment had grown to 136 students. In 1969, the first class graduated. In 1983, the Sisters of St. Francis were replaced by the School Sisters of Notre Dame.
