The Treetop ABA Therapy: The right support at the right time.

Start ABA Today

A modern model for ABA care

Treetop ABA brings together committed clinicians, expert leadership, and the resources to deliver top-quality care across 13 states – without losing what matters to families. Under new ownership since 2025, we’ve united three established ABA organizations with a shared belief: quality therapy starts with strong clinical leadership and is strengthened by the right systems behind it.

Led by clinicians, focused on children.

As a BCBA-led organization, therapy programs are evidence-based and built around measurable goals that are personal to your child. Before skill-building, our therapists focus on developing trusting relationships with you and your child.

Built to support families.

At the same time, our years of experience behind-the-scenes supports better care, with state-of-the-art systems and smooth processes that enable families to start therapy sooner, and empower our clinicians to do their best work.

Why families love Treetop

Hear it from them!

I’m loving this place so far & everybody who works here. My son has been having a difficult time with transitioning to coming to ABA vs staying home, but everyone here has been so welcoming & helpful. They’re so encouraging & definitely are helping give me peace of mind. I’d recommend this place to everyone I know.

Treetop has truly been a blessing for our family. The whole team is phenomenal. When my son started, he was nonverbal. Now he’s making huge progress: counting, saying more words, and communicating so much better. His motor skills and potty training have improved too. I recommend Treetop at the highest level to any mom, dad, or parent whose child needs ABA. They are sweet, kind, and most importantly, they truly love their kids and support them every step of the way. We’d give them 50 stars!
