Saint Thomas More Catholic School opened in 1960 and was operated by the Sisters of Saint Joseph. Grades Kindergarten through 8th began with 708 students.
Saint Thomas More Parish was carved out of the existing Our Lady of Mercy Parish. Archbishop Rummel was petitioned to approve the creation of a new parish which he did. At the time, Sir Thomas More had recently been canonized and it seemed appropriate to name the parish after him. He was a layman, husband and parent who lived a devout life and was a lawyer and an official of the government. He died defending the Church which he loved. The parishioners in the newly established parish identified with him as they had a strong interest in securing a Catholic education for their children. The founding pastor was Monsignor Andrew Frey.
