He was a member of the Faculty of the Theology Department at Holy Cross and served as Vice President and Dean of College. He also served as Chair of Religious Studies and Theology. During his presidency, he and Peter Likins of Lehigh University were the two college presidents contacted by the Ivy League in the first stage of the formation of the Patriot League during the early 1980s.[3] Following his retirement as President in 1994, Brooks remained at the College as President Emeritus.
In 1968, Brooks recruited a group of young African-American men to study at Holy Cross. A 2007 article in BusinessWeek suggested that "Brooks helped shape an exceptional group of overachievers", including Clarence Thomas and Edward P. Jones as chronicled in the 2012 book on the integration of Holy Cross, "Fraternity" by Diane Brady.[4]
Brooks Music Hall is named in honor John Brooks, one of the only halls named after a person while they were alive. Construction of the building was overseen by Father Brooks' nephew Paul F. Brooks Jr.
