snowgirl - my ds is also doing visual tracking therapy right now and we found our therapist on the website mentioned above. He has also shown great improvement and I am very excited about this. He was 9 before we discovered what was wrong so I am very happy you found help at a younger age. I think that would have saved us alot of grief.
I too am looking forward to when we're done. He retested a couple of weeks ago and they think we're about half way there.
I'm glad things are working out for you too!
