This presentation is tailored for professionals and community members who are interested in gaining insights into San Diego START's efforts to provide support for individuals and systems navigating both Intellectual and Developmental Disabilities (IDD), including Autism Spectrum Disorder (ASD), and co-occurring mental health vulnerabilities. Our objective is to share vital information about ASD, the START (Systemic, Therapeutic, Assessment, Resources, and Treatment) Model, and San Diego START’s efforts in working with this population. Throughout the presentation, we will showcase the systemic and strength-based approaches utilized by San Diego START’s clinical teams. Additionally, we will highlight START's guiding principles and the therapeutic models employed by San Diego START’s Clinical Team to enhance the effectiveness of care systems for individuals navigating both IDD – including ASD -- and co-occurring complex mental health vulnerabilities.
