He became Dean of the Drew Theological Seminary, Drew University, Madison, New Jersey in 1947. Just one year later he was offered the Presidency of the University upon the retirement of President Arlo Ayres Brown. As the seventh President of Drew, renovating and rebuilding the antiquated campus became his greatest legacy. New buildings, such as the Baldwin Gymnasium and many dormitories, were completed under his leadership. A graduate study curriculum was also instituted. Upon his election to the Episcopacy, Bishop Holloway was assigned to West Virginia.
