BDI employs four Licensed Psychologists all trained in applied behavior analysis. Many of our senior staff are board certified in behavior analysis as well. This team of highly trained staff work closely together to optimize each child’s progress—so each child reaches their own capacity for learning: those who reach “best outcome” and those who don’t. For those children who may not reach best outcome, we continue working with them but focus our treatment on critical communication skills and functional skills, often tailoring their program to address any aberrant behavior they may display.


BDI is committed to each child we serve, and have the same commitment to our staff. The majority of our senior staff team have been with Behavioral Dimensions for 10 years or more. This has enabled us to constantly improve our program so more children benefit. We have also branched out and provide a variety of other services, to older children with autism, and children and adolescents with behavior and mental health problems.
