Sorry to hear you are going through that right now. Some people just don't understand our children. It can be so sad and frustrating. That woman is the opposite of everything you would want for your child. I am sorry. I am sure you will eventually find the right environment. It is great that he seems happy there, but he could change. My DD4 started "dumbing herself down" (sorry if that sounds awful) at school so that she fit in in preschool and is just starting to share more of herself with people. It will get better. It seems preschool can be a tough time for kids who are very advanced.
