The philosophy of St Mark's is "The Family that Changes" and the primary aim of the St Mark's Therapeutic Community is: “To empower, reconnect & give hope. Enabling lifelong change to create a positive future for individuals and whānau impacted by Alcohol & Drug Addiction” We do this by changing the individual's lifestyle through the therapeutic community working together towards helping themselves, to help each other. St Mark's treatment model is based around Te Whare tapa Wha, a Māori model which promotes the four pillars of Health Mind, Body, Spirit, family and community.
