Alaric Tan
Founder and Executive Director, The Greenhouse

Alaric Tan is Founder and Executive Director of The Greenhouse, a substance use recovery centre for marginalised and vulnerable communities that find it especially hard to seek help. As a survivor of abuse and harmful attempts to change his sexual orientation during youth, he often shares his lived experience of trauma, drug addiction and recovery publicly with others, to help them understand addiction as both a mental health and public health issue. Underlying all of the work that he does, he is a simple believer that anyone who wishes to heal from trauma and outgrow addiction deserves competent and compassionate care that will not further stigmatise or retraumatise them.
