His contributions to the field of neurosurgery are recorded in more than 100 published articles and books. Cahill's publications can be viewed online. He was loved by his residents, respected by his colleagues, and feared by any who attempted to challenge his breadth and depth of knowledge. He is remembered as a consummate surgeon, devoted to family and patients.

The Cahill Symposium was originally designed for practicing physicians in neurosurgery, neurology, spine surgery and nurses/physician assistants.
