About Us

Our Mission

The mission of Step By Step Behavioral Solutions is to provide a range of clinical and consultative services to children with autism and other neurological disorders and their families. With all of the services that we provide, the child and family is always the first priority, and our goal is to help each child reach their fullest potential.


Step By Step Behavioral Solutions is committed to providing services that are evidence-based and rely on the principles of applied behavior analysis. Applied behavior analysis is based on the scientific principles of behavior and learning and relies on over 40 years of research. Applied behavior analysis is the application of these principles to humans in order to teach skills and make changes in behaviors that are meaningful to the individual. Additionally, there is extensive evidence to support the use of applied behavior analytic methodology to make socially significant changes in the lives of individuals with autism.
