Dr. William Van Ornum

Professor of Psychology


After a background in STEM-related courses and computer programming, I turned to clinical psychology, receiving a Ph.D. from Loyola University of Chicago. An internship at Astor Home for Children led me to the Hudson Valley. I am a licensed psychologist, have had a private practice and done consulting, particularly in the area of developmental disabilities.

Marist students are great! I enjoy seeing them succeed, winning awards, and experience their first burst of professional success when they make a conference presentation.

I have taught about 15 different courses, and currently teach Abnormal Psychology, Exceptional Child, and Measurement and Evaluation.

I look forward to every school year!
