Why Boulder Parents Choose Us for Their Kids

  • If you’ve heard horror stories about rigid drills at a desk, take a deep breath. That’s not us. We specialize in pediatric, play-based care.

    We follow the latest science in Naturalistic Developmental Behavioral Interventions (NDBI).

    The Data: 2024 research confirms that children learn best through play, not rote memorization.

    The Result: Skills that actually stick—whether your child is navigating the playground at Scott Carpenter Park or watching the street performers on Pearl Street.

    "We don't force compliance. We build confidence."

Local Therapy That Fits Your Child’s Life

We are locals who get it. We know that for a child, a "successful session" isn't about sitting still.

It looks like:

Handling transitions at Valmont Bike Park without a meltdown.

Learning safety skills for walking near Boulder Creek.

Building communication so they can tell you what they need before frustration hits.

Our RBTs are trained specifically for pediatric needs.

What Colorado 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."
