Julie Preuss is a BCBA in St. Louis, Mo. During her psychology undergrad training, she focused her upper level classes on behavioral neuroscience and social psychology. She was a research assistant for Dr. Bettina Casad, in her social psychology lab, at the University of Missouri-St. Louis. That experience taught Julie the importance of physiological behavior data when assessing complicated human interactions, such as perceived heart rate, sweat conduction, and blood pressure levels. Additionally, she learned about the complicated science behind nonverbal behavior, by Dr. Miles Patterson, past editor of the Journal of Nonverbal Behavior. During her graduate program in behavior analysis, Julie worked with adults and children who had Autism, psychiatric conditions, and dual diagnosis. She is also a committee member of the Behavior Support Review Committee at the Missouri Department of Mental Health, which provides support and review of behavior plans that are not reaching predetermined goals. Her approach to behavior analytic services is focused on integrative behavioral packages that use evidence-based practices, centering on the perception and experience of adult and pediatric clients to promote behavioral changes guided by a person-centered approach.
