Dr. Stacer and Fred Stemen developed the material for the program based on proven strategies that are unconventional and help parents to think completely differently once they begin working with Dr. Stacer. She and Fred developed approaches using the concepts that parents involved in conflictual cases have high levels of anxiety that need to be calmed down, using techniques that immediately help them to think clearer and more focused. She helps parents to redirect their anger at the other parent toward focusing instead on strategies to get closer to the children and to help them become empowered. She works with parents who are often frightened by the other parent, (who may be a high conflict personality) and she refocuses these parents on ways to let go of the conflict and focus on creating a new life away from the fight.

She teaches skills, strategies and scripts to help both parents and children get out of the middle of the conflict. Stacer uses stories and proven exercises to help parents calm down, eliminate their child sharing fears, redirect their anger from the fight, to getting out of the court system. She teaches parents successful strategies to create powerful connections with their children so they remain closer to them and are not damaged by the conflict. She offers insight and helpful techniques to coparent more effectively with a difficult or high conflict parent.
