All my experiences with family service agencies were through live seminars. It was a major addition of some street level experience to add to their clinical teenage behavioral management strategies.
Family service agencies have a unique problem they need to solve as they are not in the home of the troubled teenagers all the time to assist the parents with how to deal with a rebellious teen. So our focus was on giving their workers an immediate response to dysfunctional and disrespectful teenage clients in their office.
If you practice the same principles all of these adults did, it is likely you will have similar results as they did.
