Both mnbh and myself are former Three Springs employees.
Your child at best will be able to see the onsite therapist maybe once a month. Perhaps for 20 minutes at a time. Mostly they see the pyschologist to ascertain if the child's medication needs to be adjusted. Abuse is handled in group, and under certain circumstances in a speciality group. I can't speak for North Carolina, but in the facility I was employed this group for abuse issues was moderated by two people with no actual formal training.
Substance abuse issues will be handled with a AA/NA style of treatment. At PRVB's it proved to be very unsuccessful given the rate of relapses amongst graduates of the program.
Groups are supervised by a person with 100 hours of training and any sort of Bachelor's degree. Child care experience is considered a bonus. The 100 hours of training is practically useless and it pays scant attention to key points like verbal de-escalation, group process, and maintaining standards of the program. Most counselors that came to my group from training were useless until I trained them myself. That is if they stayed.
Your child who is probably suffering from all sorts of abandonment issues is going all his worst fears of you abandoning him confirmed. In your child's mind he is expecting you to do more of the same that has happened to him. I strongly suggest you avoid a TBS program as his psychological needs will not be addressed in any shape way or form. He will be broken down, shuffled around, and have himself remade into a program drone. That fire he has in his eyes is going to be extinguished and he will come back to you a barren husk of humanity.
If you think this is absurd ranting I promise you it isn't. I know it is true because I helped the process.
Another thing this if fornits. If you don't like who responds to your questions take them elsewhere. I moderate this specific board with the expectation that all are welcome to participate with the exception of one person, The moron known as the Who, providing they contribute in an appropriate manner.
I make the decisions here as to what is appropriate.
If that is to much for you then take a few minutes to think about it. Your frustrations regarding it will be nothing compared to the frustrations you are going to heap on your kid.
