Raynor managed Marquette University from 1965 to 1990, which is the longest tenure of any president in Marquette's history. During Raynor's tenure, the university added several graduate and professional programs, including doctoral programs in biology, chemistry, English, history, mathematics and engineering. From 1948 to 1951, Raynor taught and served as vice principal at St. Louis University High School.
Raynor was ordained as a priest in 1954. Five years later, he received a Doctorate in higher education from the University of Chicago. Father Raynor joined Marquette's faculty in 1960 to serve as assistant dean of the university's College of Liberal Arts (now the Helen Way Klingler College of Arts and Sciences).
He moved to the position of academic vice president in 1952, at which time he became Marquette's twentieth president. He also taught at the university's School of Education. The campus also nearly tripled in size from 26 to 80 acres during his presidency.
Near the end of Raynor's tenure, the Campaign for Marquette (1985–1990) fund drive raised more than $130 million for the school. Raynor retired as president in 1990, and became university chancellor a year later, assisting his successor and participating in university fundraising. After his third major heart surgery and a battle with cancer, Raynor died on November 14, 1997.
