Hi! I believe I can be of help with this issue. First, let me say I can imagine how worrisome and distressing this situation must be for you. Your grandson is truly out of control and I think you are correct to seek a more intensive treatment than the psychiatrist seems to be doing. Finding a suitable place for your grandson is both a matter of making sure of the quality of the facility and the affordability to you. So let me give you a few resources that are reputable.
The facility, however, that Dr. Phil recommends is called Turn-About Ranch. They have both a short term program and a 100 day program. They focus on the kids working with horses, which I can tell you is a model I support very much. I don't use Equine Therapy but I have attended conferences and met professionals who do and have been impressed with the reports I have received. Here's the address for admissions to the Ranch:
You can browse their site and get a sense of what their program is like.
The parent organization of Turnabout Ranch is called Aspen Education. They have a number of different facilities and programs with different focus and age groups served. Here is their web site you can browse. When you see a school or program that interests you, you can go directly to its site from this one:
You should also look at Abundant Life Academy's (It's very Christian in its orientation) boy's boarding schools: http://www.abundantlifeacademy.com/
The Christian boarding schools have a good track record and they often are less expensive. It is also easier to find funding help on your own town through your own church to help with expenses by asking the church membership to help sponsor him.
Okay, I wish you the very best!
