Integrating play therapy and sand tray in the treatment process for children and adolescents helps them resolve their mental health challenges in a way that meets their unique developmental needs in treatment. This in-person, experiential training will help child/adolescent mental health professionals and play therapists understand the developmental aspects of working with children and adolescents using sand tray in play therapy treatment. Participants will learn how to identify clinically relevant themes, how to process sand trays with clients, and how to therapeutically “hold” client sand trays in play therapy. Participants will also gain practical tips for how to document their play therapy sessions when using sand tray. Through this in-person two-day didactic and experiential training, participants will create and process their own sand trays and recognize how the therapeutic powers of play are accessed in the play therapy process.
