Sister María Guadalupe Valle was born in Cuernavaca, Morelos. She was raised in a family that was active in their parish and were known for their physical and spiritual aid to their neighbors. She thought about entering religious life when she was 18, and 10 years later the impulse returned, especially after she made some vocation retreats and became acquainted with various religious congregations. She entered at age 32. She currently works in the parish of Cristo Rey y Santa Beatríz de Silva in Colonia Pradera, Mexico City.
