Our ABA Process

Let’s Talk

We’ll give you a call to learn about your child, explain how ABA works, and answer any questions.

Personalized Assessment

Our licensed BCBA will guide you through the assessment and develop a custom treatment plan.

Therapy Begins

We match you with the right therapist and begin your ABA services based on your schedule.

Can ABA therapy be done at home?

Yes, in-home ABA is what we do best, and for many families in Nashua, it's where real breakthroughs happen. I’ve worked with dozens of families in small apartments, busy households, and chaotic schedules, and it can feel like a lot at first. But we tailor the schedule, match the therapist to your comfort level, and stay flexible, because if it doesn’t work for your home life, it doesn’t work at all.

What Families Are Saying

"We didn’t expect results this quickly. Her meltdowns used to last 45 minutes — now they last 5, and she can tell us what’s wrong."
‍
"Our son used to get overwhelmed by transitions. Now he can leave the park without a fight. That’s huge."
‍
"ABA at home changed everything. It’s calmer now — not perfect, but better. That’s all we wanted."
