Thanks everyone! So should I go to his regular ped first to see if she recommends anyone? I don't need a "referral" to see a specialist, so that's not an issue.

The good thing is, at the school they're attending next year, they have a "therapy room" on-site. I don't know if that's different than regular schools, but it's certainly different than they have in the school they attend now.

He's not flipping out all of the time, just in certain occasions.

Thanks so much for your input, I've been debating this for a while (hence the reason we had him tested with the diagnostician in the first place). But ever since he's started other sports other than swimming, I've noticed it even more.
