mamabird, I am also in the Twin Cities suburbs with a 2E child (D15, Asperger's and a non-verbal learning diasability). Agree with kim, MCGT is a great local resource! Sorry I can't provide a specific name of someone for you (our testing has been sort of scattered, IQ testing by someone with experience with gifted kids, but the 2E part by someone else...), but I bet the MCGT Yahoo! group would have some recommendations for sure.

I don't actually belong to a chapter, never have although I have been an MCGT member for about 12 years. I just use the online resources, and have enjoyed their annual conference in the past (haven't been lately).
