My DS6 is in OT through Children's Healthcare of Atlanta (CHOA). Our insurance covers it completely, and they are wonderful! It took a while to get it scheduled, but the assessment was about 2 hours. They have a long wait, and it took a couple of months from there to get the OT started. He has gone almost every week for about 4 months, and the progress is dramatic. His therapist wants to start going every other week. We have been very, very happy with them.
