Following the completion of his degree he spent many years in the private practice of medicine in Chicago. Dr. Santangelo was a professor of Dentistry at Loyola University, was Chairman of the Department of Radiology, and Associate Dean at Loyola University Dental School. He authored numerous articles for various dental journals and was a speaker for dental symposiums across the country. He was the Secretary and then Director of the American Dental Association.

In later years Mario came back to the area to take care of his brother, Vincent Santangelo and his sister, Antonette Santangelo and he decided to reside in Boardman. Of all his life's passions Mario was most devoted to the Catholic Church and Our Lady of Mount Carmel Basilica in particular.
