This 1-day training is designed to raise levels of practical knowledge among substance use treatment providers about the identities, needs, and concerns of transgender clients, and to transmit best practices for professional interactions and communications. The program uses multiple learning modalities (video, interactive small and large group activities, and structured dialogue), to engage participants in an upbeat, positive atmosphere and encourage immediate application of the new skills they gain. This is the sixth required module in the Sexual Health in Recovery Facilitator Certification course.
