Cofiño was the first University Professor of Pediatrics in the Universidad de San Carlos de Guatemala medical school, where he taught for 24 years. He was a member of the American Academy of Pediatrics and the French Language Association of Pediatrics.

He was involved in several medical positions.

He was also much involved in the movement to outlaw abortion, considered "one of the founders of the pro-life campaign" in Guatemala.^{[citation needed]}

In 1956 he requested admission to Opus Dei. Through this, he was said to have learned how to sanctify his work, "imbuing his exquisite social sensibility and his great professional sense with an urgent zeal for the rechristianization of society."^[2]

When he was 80 years old, he was diagnosed with cancer in the jaw. He continued working until he finally succumbed to a resurgence of the cancer when he was 92.

Cofiño's cause for canonization was opened on July 31, 2000, nine years after his death. On December 14, 2023, Pope Francis approved Cofiño's practice of heroic virtues and declared him Venerable.^[3]
