Here are 2 great links for you to find a wide range of resources for ASD children including things like where is best to get their hair cut, go to the Dentist and so on. All places listed are experienced with Autism:
-click on your state and it will bring you to a wide range of services.
-click on the service you are looking for and it will give you a list of providers experienced in that specific service with Autism. I frequent the link listed above. It's how I found where to get my sons hair cut (his extreme trigger), his pediatrician, where I could get an Autism evaluation and his dentist!
