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. For that same period of time there has also been troubled teens recovering and becoming entirely turned around in their behaviour.
If you practice the same principles that all of these adults did you can expect similar results.
