We see Dr. Nhung Tran, Developmental Pediatrician, at Round Rock Specialty Clinic, about every 2-3 months. Has he been evaluated at the Autism Community Network? http://www.acn-sa.org/
That would be the best place to start in SA. There are some dentists in SA that work with special needs children, but don't take medicaid. I take Bailey to the Dental Clinic at Children's Hospital (formerly Santa Rosa). Any Baby Can also offers parent training etc. for parents of children with autism and provides free childcare while you attend. Hope this helps
