Since the first Circle of Trust retreat was offered in 2005, the Center for Courage & Renewal (CCR) and other individual facilitators across the United States, Canada, and Australia have continued to offer many cross-professional retreats, as they have proven extremely popular. They are designed for people from any profession who want to deepen their interactions and conversations in their workplaces, relationships, and communities. Each of the Circle of Trust retreats includes guidelines, sometimes called touchstones or boundary markers, that establish norms and respectful boundaries for working together. This chapter reports the findings of an evaluation that explored the impact of Circle of Trust retreats and the learning and personal and professional applications in the lives of retreat participants. The Center for Courage & Renewal began offering Circle of Trust cross-professional retreats in 2005 to provide people from any profession with an opportunity to experience a "circle of trust" as described by Parker J. Palmer in his 2004 book, "A Hidden Wholeness: The Journey Toward an Undivided Life."
