Matt (2)

Matthew Ryan – Vice Chairperson

Matt is currently working as a Key Program Worker in the new Mallee AOD Recovery Program at Casuarina Prison. Matt recently graduated with a Bachelor of Behavioral Science (with Distinction) along with achieving Notre Dame University’s ‘Heart Award’ for his commitment to social justice, community spirit and reconciliation. Matt applies these skills in his role as AODCCC Vice-Chairperson to provide collaborative conversations and empowerment opportunities for AODCCC members. He is passionate about developing the voice, interests and opportunities for AOD consumers, their families, carers or friends individually, in the community and within governance circles. Matt believes that AOD consumers and the community that surround them are experts-by-experience in their lived involvement and for that reason are best placed to authentically be included to unpack a lived experience in decision-making circles. As someone with 20 years lived experience as an AOD consumer, developing these conversations and critically examining policies, plans and service provision, are issues close to his heart. Understanding and deconstructing the stigma that exists around AOD use in all levels of society, remains a consistent goal because he believes that the voice of AOD consumers and their support networks can be a powerful force of positive change in the community and in the lives of individuals.
