She was born in Ólvega (Soria) on November 24, 1930. She spent her childhood in Tudela (Navarra). Since she was a child, she felt the missionary vocation under the influence of the spirit of Saint Francis Xavier. She studied Chemistry at the University of Madrid. For a few years, she was part of the “Institute of Missionaries of Christ Jesus” and studied Theology in Valencia. In 1964, she met Kiko Argüello in the Palomeras Altas barracks in Madrid, and after announcing the Gospel to the poor among whom they lived, the Lord lead them to a theological-catechetical synthesis based on the Word of God, the Liturgy and the Community, which will become the basis of the Neocatechumenal Way, whose Statute was approved by the Holy See in 2008. The then-Archbishop of Madrid, D. Casimiro Morcillo, encourages them to spread it in the parishes. For more than 50 years, together with Kiko Argüello, she gave her life announcing the Gospel throughout the world. She had an immense love for Jesus Christ, the Church, the Virgin, the Pope, the Liturgy, Sacred Scripture and the Hebrew roots of Christianity. She died in Madrid on July 19, 2016.
