We use Doctor Gordon and have done so for 13 years. We have two boys with moderate to severe autism and Doctor Gordon is a godsend. His son has moderate to severe autism and this experience helps him as an adviser to parents. He has helped us through so many situations and experiences--dealing with sleeplessness, mood swings, inappropriate behaviors, IEPs and practical tips, such as dealing with family trips.
Most importantly talking with him is good therapy for my wife, my daughter and myself.
