Cheryl S. Sharp is a Senior Advisor for Trauma-Informed Services at the National Council with over 30 years of experience working with adult trauma survivors. She provides training and expertise on trauma-informed crisis services and suicide prevention initiatives. Trauma results from events that profoundly impact an individual's psychological development and well-being, often involving physiological, social, or spiritual effects. A trauma-informed approach recognizes how trauma affects individuals and systems, avoids re-traumatization, and applies practices grounded in understanding trauma. The OSA model for adopting trauma-informed care includes domains for screening, consumer-driven services, workforce development, best practices, safety, community partnerships, and performance improvement.
