Lifespan Integration (LI) is a gentle, body-based therapeutic method developed in 2002 by Peggy Pace. It helps individuals heal from trauma and grief by integrating past experiences into a coherent life narrative without re-traumatizing them. LI involves creating a timeline of significant life events and guiding clients through visualizations that connect past and present selves. This approach, informed by neuroscience, rewires the brain for healthier emotional responses. LI's non-invasive, adaptable nature makes it particularly effective for trauma work, promoting resilience and holistic healing.
