Adjunct Professor of Science

A native of Ohio, Dr. Loyal Tillotson, completed his medical training and went on to conduct graduate and postgraduate research on the cellular and molecular biology of colon cancer. His postgraduate clinical training included an Internal Medicine Residency at Duke University Medical Center and Gastroenterology Fellowship at the Massachusetts General Hospital in Boston. Subsequently, he has had faculty appointments at Harvard Medical School and the University of North Carolina at Chapel Hill.

Prior to moving to South Dakota, Dr. Tillotson conducted biomedical research in the area of genetic regulation of intestinal growth factors and oncogenesis. His interest going forward with John Witherspoon College is to structure the science courses so as to examine key discoveries within a classical education model. This will entail investigation of the history of science, methods employed by great scientists and the context of their discoveries within a Christian worldview.

In addition to these professional activities, Dr. Tillotson has been a long-standing member of the Christian Medical and Dental Association. He previously served on the Rapid City Christian School Board, and currently serves on the Board of John Witherspoon College. He is married to Emily Graebner Tillotson, and they have two children.
