Padre José María is from Tablada de Lurin (Lima), Peru. He felt the calling to the priesthood from a very young age. He had entered a diocesan seminary in northern Peru, but was unable to continue after the first year. A friend of his told him about a new community near Lima and he introduced himself to Padre Martín shortly afterward. He was one of the first vocations after the community was founded.

He chose his name because he has a great devotion to Saint Joseph and the Virgin Mary. He was ordained as a priest on 26 April 2014 along with Padre Pedro. They are the first two ordained priests since the community was started by Padre Martín.
