Hi, K., I'm in Denver with a nearly 17 year old daughter with Asperger's among other things. She is also very gifted. I recommend you look into Denver Academy - an excellent private school for kids with learning differences of all kinds. My daughter attended middle school there and she really blossomed in terms of self-esteem, confidence and self-advocacy skills. She returned to public school for high school, primarily because she needed more advanced and AP courses, and she has been very successful there.
I am a clinical psychologist who specializes in working with families like ours, and I run a parent support group for parents of kids with Asperger's, PDD or nonverbal learning disability. I'd love to have you join us when you move!
take care, S.
