Hi--

Another pro-ABA voice here. We started late (age 5.5) but it is very effective.

I understand that Tufts U. has a center for autism spectrum disorders, but I don't know the details. You may find more resources listed at

http://www.aspergersyndrome.org/Home.aspx

Links on the left side of the page go to pages with geographically specific resources. There is also a good forum on this site; there is a lot of overlap between Asperger's and PDD-NOS.

HTH,
DeeDee
