Center-based in Northwest Indiana
18 months – 8 years

Immediate access to care
Early intervention makes all the difference. With conveniently located autism therapy centers near you, your child can start ABA therapy right away.
Diagnostic support
You don’t have to wait for answers. If your child has many of the early signs of autism, we can help them get evaluated.
Family Guidance
Parents and caregivers play an important role in their child’s growth. Every care plan includes twice-a-month Family Guidance sessions led by a BCBA, giving parents practical strategies they can use during therapy and in daily routines at home.
ABC had been life changing for both us, and our child. They have been there every step of the way, from the initial testing/diagnosis, to daily check ins and updates at pick up. They helped us with insurance questions and issues, which are overwhelming all on their own. We’ve seen so many improvements in our little one. The therapists and everyone at the facility go above and beyond. I can’t recommend them enough!!
Insurance made simple
We accept most major plans, guide families through paperwork, and can provide financial assistance for out-of-pocket expenses.
Coordinated care
We collaborate with your child’s speech, occupational, feeding, and physical therapists to provide sessions directly in our centers. This allows your child to access other services in a familiar environment while minimizing unnecessary transitions and travel.
School readiness support
Center-based ABA therapy helps children build the skills they need for school, such as communication, social interaction, and executive function. For school-age children, ABC Academy continues that support by bridging the gap between therapy and the classroom.

Frequently asked questions
What is ABA therapy and how does it work?
Applied behavior analysis therapy is a research-backed method that helps children diagnosed with autism learn new skills and reduce behaviors that may make learning harder. With ABA, children can improve communication, build daily living skills, and better understand their emotions. Our ABA therapists utilize different strategies, like Discrete Trial Teaching (DTT) and Natural Environment Teaching (NET), to support each child’s progress. Therapy is delivered through a compassionate care framework and emphasizes the child’s individual needs and goals.
Will my child be sitting at a table all day during ABA therapy?
No way! At ABC, learning happens through a variety of engaging activities. While table time can be part of learning school readiness skills, children also enjoy:
- Circle Time with therapists and peers
- “Eats and Crafts” spaces for hands-on activities
- Group exercise, sensory rooms, and play-based learning
Therapy is designed to be fun, active, and motivating.
Is ABA therapy effective for autism?
Yes! Every autistic child is unique, and some children experience more significant progress with ABA therapy than others. However, studies show that children who receive two or more years of intensive behavioral interventions, including ABA therapy, can often participate in school and social activities at the same level as their peers.
