Our Story

Sandbox ABA

Sandbox ABA was founded in Austin TX 2012 by Rebecca Ryan, who as a parent of a child with autism and with years of experience in both Applied Behavioral Analysis and legal fields, wanted to provide a locally-based, family-oriented center that would provide excellent, progressive ABA therapy to children with autism.

Having had to navigate the difficult in’s and out’s in finding quality intervention for her son and family, Rebecca loves to serve as a resource for the many needs a child and family will need in accessing treatment and support.

Sandbox ABA strives to collaborate with other professionals with applied behavioral therapy as well as speech and occupational therapies. We also work with schools and families to understand the services that would be best tailored to the child’s educational needs; we provide training and support to schools as well as an understanding the challenges that come with insurance coverage. 

Supporting families is part of our quality assurance by determining the scope of coverage for their child. We will also assist the family and their insurance provider to achieve appropriate coverage for the child to make sure that they get the necessary education to succeed.

We are excited to partner with families through Applied Behavioral therapy to help them achieve success in helping their child grow to their fullest potential.
