Our son has made outstanding progress during the last year, he is finally coming out of his shell and engaging in open play with other children. Thank you so much ABC for helping us!
The ABA therapy provided here has been a game changer for my son, who in his own words said "I've learned how to make friends and finally enjoy school." The staff are delightful and knowledgeable, and patiently worked with us as we navigated our own journey through the world of ABA. The staff at ABC gave our family the tools we needed to improve our son's life and ours. It's definitely a team effort and parents need to be willing to put in the investment of learning too, but it's absolutely worth it. We even miss coming here as we had such positive interactions with the staff! Thank you, ABC!

Who can diagnose autism?
In the U.S., autism is diagnosed by qualified medical and mental health professionals through a comprehensive evaluation. This process may include direct observation, developmental history, caregiver interviews, and standardized diagnostic tools to determine whether a child meets criteria for autism spectrum disorder (ASD). Many children can be evaluated as early as age 2.
Professionals who may diagnose autism include:
- Developmental pediatricians
- Child psychologists or neuropsychologists
- Child psychiatrists
- Pediatric neurologists
BCBAs may support the evaluation process, but a formal autism diagnosis is typically made by one of the specialists listed above.
Screening tools, such as the M-CHAT-R or CAST can help identify signs that a child may be at risk for autism. However, a full autism evaluation is required to make a formal diagnosis.
What is the best treatment for autism?
At Action Behavior, we provide applied behavior analysis (ABA) therapy, a gold standard treatment for autism. ABA therapy for autism is evidence-based, which means it has been tested and shown to be effective through multiple scientific studies.
Our internal data show that children with autism who require comprehensive ABA therapy (25 or more hours per week) experience, on average, an 86% reduction in challenging behaviors such as aggression, elopement, property destruction, and self-injury. Most of this progress happens within the first year of treatment. Even as therapy hours are gradually reduced by about 20% over time, children continue to show lasting improvements. See more of our outcomes research here.
What is ABA therapy and how does it work?
Applied behavior analysis (ABA) therapy is a gold standard in care for children diagnosed with autism spectrum disorder (ASD). It helps children build practical skills and reduce behaviors that may make learning harder. Through ABA therapy, children can improve communication, develop self-care routines, and better manage emotions.
At Action Behavior Centers (ABC), our Board Certified Behavior Analysts® (BCBAs®) and Registered Behavior Technicians® (RBTs®) use positive reinforcement and individualized strategies to support growth. Families are active partners in therapy, working with our clinical team to set goals and track progress.
