Program Information At Lively Behavioral Solutions we use applied behavior analysis (ABA) which is a scientific approach to understanding and changing behavior used to treat a variety of conditions such as autism, developmental disabilities, and mental health issues. ABA professionals, such as Board Certified Behavior Analysts (BCBAs), Registered Behavior Technicians (RBTs), and Mid-Tier Supervisors, design and implement behavior interventions for individuals of all ages and abilities. A career in ABA offers the opportunity to make a positive impact on people's lives, work with a diverse range of clients, and be part of a growing field with high demand for professionals.
