​
Dr. Blejewski is a licensed psychologist and board certified behavior analyst at the doctoral level. He earned a Master of Arts degree in Clinical Psychology with a concentration in Applied Behavior Analysis from the University of North Carolina Wilmington under the supervision of Dr. Carole Van Camp. He earned a doctoral degree in Clinical Psychology with a concentration in applied behavior analysis from the University of North Carolina Wilmington under the supervision of Dr. Raymond Pitts. He completed a postdoctoral fellowship at the Center for Pediatric Behavioral Health. He has experience addressing both common behavior problems and more severe challenging behavior in both clinic and school setting at The New England Center for Children and Center for Pediatric Behavioral Health. He has conducted research evaluating factors involved in impulsive choice and the use of assessment to increase physical activity. Dr. Blejewski has co-authored publications in Behavior Analysis: Research and Practice and the Journal of the Experimental Analysis of Behavior.
