Goodluck in finding a place. Im not in the US but I have read about private retreats that do that kind of thing. The problem is, they are very expensive and cannot hold him if he decides he wants out. Also there might be problems with his age. Do you think you could do it within the family? Send him to his aunt or someone who is committed to helping him? Work with a seperete dietitian and nathropath among yourselves? Im sorry I cant be of more help.
