Although he received a strong Catholic formation from his par­ents, by the time he was in high school, Dr. Taylor O’Neill was no longer a practicing Catholic. By God’s grace, however, a literature teacher brought him back to the Faith — by introducing him to the Great Books.

“He essentially taught us the Catholic faith through great works of literature, and he would work in Plato and Aristo­tle,” recalls Dr. O’Neill, a tutor om the New England campus. The experi­ence ignited his curiosity for learning. “I knew that I wanted to study philosophy or theology after that, and my spiritual journey was molded by the liberal arts.”

Upon graduating from the University of Wisconsin-Oshkosh, Dr. O’Neill en­rolled in graduate school at The Catholic University of America. It was during this time that he met his future wife, Eliza­beth, through a Catholic group in Wash­ington, D.C., where she was working as a chemist. The couple married a short time after in 2011 and are today the parents of six children.

After completing his master’s degree in historical and systematic theology at CUA, Dr. O’Neill earned a doctorate in theology at Ave Maria University in Florida. From there, he and his family moved to Cedar Rapids, Iowa, where he spent the next four years as a professor of theology at Mount Mercy University.

Having joined the Thomas Aquinas College teaching faculty in 2021, he is now delighted to teach from the same Great Books that proved so instrumen­tal in his own formation. “I don’t know of anywhere else in the world that is going to give students the opportunity, the space, and the guidance to spend four years thinking and contemplating the highest things in life,” he says. “Every student here is so invested to contem­plate the highest things for the sake of themselves and others.” He also appreciates the opportunity to teach across the disciplines in the Col­lege’s integrated curriculum.

Moreover, the northeastern climate suits him well. “The East Coast expe­riences all four seasons, and pairing that with the TAC curriculum, it made so much sense for my family and me to come to Northfield,” he says. “This is where I’m meant to be.”
