St. Brochero entered seminary at the age of 16, and was ordained a priest at the age of 26 for the Archdiocese of Cordoba.
As a priest, after teaching philosophy at a seminary for a few years, Fr. Brochero was assigned to the large diocese of St. Albert – 1,675 square miles with 10,000 far-flung parishioners in the rural, Great Highlands region of Argentina.
Not deterred by altitude, distance or bad weather, Fr. Brochero was known for riding throughout the countryside of his parish on the back of a mule to bring his people the sacraments, always wearing a poncho and sombrero in the style of a gaucho, or Argentinian cowboy.
On muleback, he carried an icon of the Blessed Virgin Mary, his Mass kit and a prayer book on his travels so that he was always prepared to offer the sacraments. He established a House of Exercises where his people could participate in spiritual exercises, and helped found a school for girls.
He is also credited with building post and telegraph stations, for building nearly 125 miles of roads, and for helping plan the railroad in the area.
"Woe if the devil is going to rob a soul from me," he is held to have said, capturing his determined spirit to be close to his people no matter what.
