Having previously reported on clinical outcomes of Adolescents and Young Adults with HIV (AYAHIV) in the Accessing Care Early (ACE) young adult transition program, we present an update, detailing the design and implementation of this multi-dimensional program, the innovations in biomedical and care delivery interventions, as well as programmatic challenges and opportunities as we evolve into a mature transition program. This workshop will use didactics and interactive presentation, case-study, transparent panel discussion and Q&A as participants engage with the ACE program’s multidisciplinary team, including an YAHIV who “came of age” in the program. The workshop will be a lively exploration of the lessons learned and an exploration of the past, present, and future of care for aging YAHIV through the lens of a seasoned transition program.
