Looking For A Special Education Tutor In Alexandria.

This is for my 23-year-old son, who has Down Syndrome. He has never been able to read per SE but can recognize letters and some written names. He used to be able to write his own name when he was still in school and writing it regularly but since leaving, he does not often have occasion to do so and now seems unable to remember how to do it. I would like instruction in writing his name, learning how to read more words and learn his address.
