For over 40 years, Father O'Neill was classics at the University of Detroit, serving on innumerable committees and as a member of the Board of Trustees for the university. He was a "founding father" of the Detroit Classical Association from its first year, 1958.With his work in classics Father O'Neill combined a keen interest in language, mental efficiency, and mental health, conducting "mental efficiency clinics" for students at the university from 1938 until 1947. His interest in analogy and thinking led him to develop creative exercises for mind development which resulted in a weekly feature in the Detroit News, "Analograms," which ran for several years in the late 1960s and early 1970s. He was much in demand as counselor and lecturer, in both the fields of classics and mental health. Except for the second item listed below, his publications are in the form of pamphlets.
