This volume brings together cutting-edge work of LGBTQ+ health experts and master clinicians on the forefront of treatment development, adaptation, and implementation. It is designed for clinicians, educators, students, and researchers who want to implement LGBTQ+ affirming practices today. Every chapter includes rich case examples, clinical dialogue, and lessons learned, with particular attention to under-represented topics (e.g., person-centered assessment, co-occurring trauma and minority stress) and groups (e.g., Black, Indigenous, and People of Color, veterans, older adults, people with disabilities).
