This state is one with the lowest autism rates in America and it is still working on and on in order to help those who are affected by autism. There are many autism therapists whose main goal is to help you feel better and provide your family with support. But, despite autism therapists, there are many organizations like Autism Society that is dedicated to improving the lives of all autistic people and Autism Speaks organization with the exact same goal.
