Dr. Spencer Dawson - Sleep Health Center I am a licensed psychologist and am board certified in Behavioral Sleep Medicine. One of the things I like most about my work is being able to help people improve their lives through better sleep. It’s amazing to witness someone go from feeling controlled by their sleep problems to being confident in their ability to improve their sleep and cope with the bad nights that become fewer and fewer.

In addition to practicing with Sleep Health Center, I am on the faculty of Indiana University. Specifically, I am Assistant Clinical Professor and Associate Director of Clinical Training in the Department of Psychological and Brain Sciences. In that position, I am responsible for training and supervising doctoral students in the clinical science program. I am actively involved in national sleep organizations including the Society of Behavioral Sleep Medicine, Board of Behavioral Sleep Medicine, and American Academy of Sleep Medicine.
