Child-based psychotherapy center for autistic child

Hi, 

We are really struggling to find a child based psychology center that deals with hundreds of kids a day, that has seen it all - hopefully integrated with a broad range of practitioners. What centers are out there? Our child is autistic (highly verbal) with behavioral and mood disorders. We've had a hard time finding places that see our type of kiddos frequently enough. And if you've been through this and have any other resources/groups that help you I would be grateful. :)

Thanks,

Mary
