The aim of this paper is to offer a definition of encounter and encounter groups based on the author’s understanding and experience as a participant and facilitator. Through reflection on experience as a participant, consideration is given to how the self-awareness and insights gained from this can shape the understanding of the role of facilitator, and how it enables what can be offered to groups as a facilitator. Theoretical contributions to understanding the role of the facilitator are considered. A strong relationship is proposed between experiences and gains as a participant and becoming an aware and helpful facilitator, arguing that experiences as a participant have the potential to contribute to the ability to trust both oneself and the facilitative potential of the group, tolerate uncertainty, hear others accurately and take risks.
