For incredible resources, I'd call Jewish Family Service of Bergen County. They are located in Teaneck. While they may or may not provide programming or offer services, they will absolutely be able to tell you who to call, where to go, etc. for everything.
For schooling -- call The Alpine Learning Center in Paramus. They will be able to tell you where to go and what to do for schooling, educational testing, etc.
For medical and related testing -- call Dr. Arnold Gold's office. He is one of the leading experts in the country, and he has an office in Englewood.
