The Mandt System is a comprehensive, integrated approach to preventing, de-escalating, and if necessary, intervening when the behavior of an individual poses a threat of harm to themselves and/or others. The focus of The Mandt System is on building healthy relationships between all the stakeholders in human service settings in order to facilitate the development of an organizational culture that provides the emotional, psychological, and physical safety needed in order to teach new behaviors to replace the behaviors that are labeled “challenging.”
