Kevin Staker is a source of assistance for families with a child with autism. The best tool he believes is a special needs trust set for the child under the living trust for the parent(s) after the parents are gone. Kevin Staker feels setting up an irrevocable trust now is rarely necessary, and does have some cost to maintain.
A good referral source is the Autism Society. They have a referral page to Kevin Staker located at http://188.8.131.52/search_site/detail.cfm?program_id=35866. This shows the confidence of the Autism Society in Kevin Staker as a source of assistance to families with children with autism.
