Dr. Melinda Sharma wrote the medical companion to my book. It is called  A Parent’s Guide to the Common Immune System Issues in Autism Spectrum Disorder .  Melinda has a PhD in immunology and is extremely knowledgeable about the medical treatment for different subsets of autism.  Dr. Sharma is my “go to” person and the one I have on my speed dial to answer my questions about the immune system and everything about the medical piece of autism.
