About Me

Gretchen A. Dittrich is a Licensed Applied Behavior Analyst (LABA) in the state of Massachusetts and a doctoral-level Board Certified Behavior Analyst® (BCBA-D®). She is an associate professor of practice and the director of mentoring and supervision in the Department of Behavior Analysis at Simmons University. Dittrich has a private practice dedicated to providing services to improve behavioral, academic, social, communication, health, vocational, and independent-living skills in people with special needs. She provides consultation, training, and workshops to parents, caregivers, educators, and specialized educational institutions on reducing problem behavior, increasing communication, alternative and augmentative communication methods, and behavior analysis. In addition, she has published and presented research nationally, focusing on reducing challenging behaviors, increasing social skills, and health promotion.

Dittrich has been working with individuals, families, and school systems since 1998, helping clients improve skill deficits and reduce unwanted or challenging behavior. While her work has focused on helping individuals with intellectual and developmental disabilities, she has also worked with individuals who have behavioral challenges, social skill deficits, and health concerns (e.g., overweight, obesity, inactivity). Dittrich’s research interests include behavioral medicine and health promotion (including the prevention and amelioration of obesity and inactivity), functional analysis of complex behaviors, social skill training, the application of behavior analytic methodologies to higher education, and verbal behavior. She is the current chair of the Behavioral Medicine Special Interest Group of the Association for Behavior Analysis International (ABAI).
