These testimonials came from an era I was doing just as much public speaking as I was doing direct consulting for parents with troubled teens.
There is a lengthy quantity of testimonials here. I wanted to display quite a few testimonials so you can learn as a parent that troubled teens have been around for a long time and in large quantities. For that same length of time, just as many troubled teens have been recovered by the adults in their life.
If you practice the same principles all of those adults did, it is likely you will have similar results.
