Hi. Frustrating, huh? I'm not a big believer in SW's, therapists, even psychiatrists knowing what is right for my own kid. Do you think your child will like camp once he's there? Make good choices? Do you know any of the counselors? My friend's son went away to a "Behavioral Therapy Camp" and a counselor sexually abused him (it was a young adult man). He came back worse than ever.
I'd say use your Mom Gut, and if this SW makes you uncomfortable, find someone else. I was thinking of sending my son to Easter Seals Camp for kids on the autism spectrum. He wouldn't like the idea of leaving, but he'd have fun once he's there. But the idea that I didn't know the counselors held me back. Maybe I'm overprotective, but he doesn't have the life/social skills to defend himself if a counselor or another kid is inappropriate. Not yet anyway.
Good luck with your decision.
