Past President:  

Dr. Nikki Powell, Ph-D, BCBA-D, COBA

Dr. Nikki Powell is a licensed psychologist and Board Certified Behavior Analyst – Doctoral (BCBA-D). She found a passion for behavior analysis early on and continued that trajectory throughout her undergraduate and graduate training. Her clinical psychology training focused heavily on cultural diversity and psychotherapeutic interventions, while her clinical work outside of school was almost entirely behavior analytic. Nikki has focused on using behavior analysis to improve access to services for populations that have traditionally been categorized as “too hard to serve.”  She has expertise in the treatment of severe behavior disorders in intellectually and developmentally delayed populations, as well as behavioral stabilization in acute psychiatric populations. Nikki is also passionate about healthcare quality improvement and had the opportunity to be trained in process and system improvement strategies. As a result, Nikki has gravitated towards opportunities to support clinical services by helping support processes and systems using quality improvement and behavior analytic sciences to create effective and efficient care models that allow for best client outcomes. Currently Nikki has sought to diversify her practice again and is enjoying working in the child welfare sector expanding access to behavioral health.
