The Autism Academy of South Carolina (AASC) is a not-for-profit organization offering individualized Applied Behavior Analysis therapy (ABA) to clients with Autism Spectrum Disorder.

AASC strives to help children with autism acquire the skills necessary to become fully capable members of their communities, ultimately able to prosper without the need for intensive intervention. Our vision is to be a model organization for individualized programs that can be replicated to serve a growing need.

Our team of highly qualified professionals is dedicated to improving the lives of children and families struggling with Autism and related disorders. We provide one-on-one and small group ABA therapy for children and adolescents age 2-21 in a center-based setting. In addition, AASC offers parent training, school consultation, social skills groups, and summer camps.



The Autism Academy of South Carolina was founded in 2010 by a group of concerned parents of children with autism and youth development professionals as a response to the rapidly growing need for resources and support to families of children diagnosed with ASD.

AASC was born out of a vision to enhance the therapy options and resources for families of children diagnosed with ASD. After searching the country in 2009 for “best practice” models, the founders, Lorri and Dan Unumb, decided to make it their mission to create a behavioral therapy center that utilized the principles of Applied Behavior Analysis to provide exceptional services for children and serve as a community resource for those impacted by autism.


Our Founders, Dan and Lorri Unumb, are parents of a son with autism. Lorri’s passion to help South Carolina families who didn’t have the means to give their children autism treatment led her to author an insurance bill in 2005. The bill would require insurers to cover evidence-based treatment of autism, including ABA.

The South Carolina General Assembly passed the bill known as “Ryan’s Law” in June 2007. Ryan’s Law served as the catalyst for a national movement toward autism insurance reform. In 2010, Lorri & Dan joined forces with a group of concerned parents of children with autism and youth development professionals to found the Autism Academy of South Carolina.

Following the passage of Ryan’s Law, Lorri Unumb joined Autism Speaks and now serves as the Vice President for State Government Affairs. In this role, she travels extensively and tirelessly with the continued drive to pass autism mandates in other states. Her passion and dedication have helped more than 35 states pass similar laws in the years since Ryan’s Law. Dan Unumb serves as the Executive Director of the Autism Legal Resource Center, which helps develop and protect the legal rights of people with autism.
