The Singapore Mental Health Conference 2021 (SMHC 2021) - co-organised by Institute of Mental Health, the Agency for Integrated Care, the National Council of Social Service and the Health Promotion Board - has grown steadily since its inception in 2013. It is now the premier interdisciplinary mental health conference in Singapore and the region. The SMHC brings together mental health, social service, and education professionals and community partners as well as advocates and users of mental health services, providing a common platform for the sharing of best practices and research findings and to network for better collaborations.
