The Koegel Autism Center is located on the University of California at Santa Barbara. The center was founded by Dr's. Robert and Lynn Koegel. If you are a Supernanny fan, you would have seen an episode with a family who had a newly diagnosed son and Dr. Lynn Koegel came with Jo Frost (aka Supernanny) to help. The Koegels have several books and manuals to their credit including Overcoming Autism written by Dr. Lynn Koegel and Claire LaZebink. All this information is available on the Center's website.
The Koegel Autism Center is dedicated to the understanding of ASD's and as they state on their website, "The major goals of the center are increasing our understanding of autism spectrum disorders, the development and implementation of state-of-the-art pivotal response treatments, as well as the improvement of elementary and secondary education efforts for children with autism and other severe disabilities. The center's primary interests lie in research and training (both pre-service and in-service), focusing on family support and on the education of children with autism in community environments and classrooms with their typically developing peers."
You can go to their website to find out more about the center and their research. They also have conferences and workshops, and if you live in the Santa Barbara area they have some services available at no cost. They have several manuals covering topics such as "Pivotal Response Training(PRT)", "Problem Behaviour", and "Toilet Training". These manuals are available for $7 (to cover copy and mailing cost).
