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

Values that guide our care
Your child is our focus
Everything we do is centered around your child. We get to know them so we can relate to them personally, with respect for their unique personality, preferences and view of the world.
Support for you, too
Parents, caregivers, and siblings of a child with autism need all the support they can get! We’re here to give that, with parent workshops, family events, and a listening ear whenever you need it.
Clear goals. Clear process.
Transparency means we make sure you’re in the loop about what therapy is targeting, how progress is measured, and when adjustments are made. We believe clarity builds trust and leads to better outcomes.
Therapy is a tool, not a lifestyle
We work with your child towards long-term independence, viewing therapy as a tool to build the vital skills that they can then take with them into life. As your child becomes more independent, we reduce hours of therapy and focus on learning to apply skills in a variety of settings.
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!
