Our People

CEO & Founder

Andrew Rigg


Andrew has a diverse professional background, having spent 12 years in broadcast media in creative roles and more than 18 years in leadership in the community sector in Australia and globally. Andrew is passionately committed to making a positive difference in the lives of others, which prompted his move from a successful career in media to the community sector.

Andrew’s professional practice is heavily influenced by principals of Asset Based Community Development and by a strong belief in the inherent power of grassroots movements to bring about positive, lasting change for communities.

With personal and professional experience in the field, Andrew is a passionate advocate for mental health, and especially in supporting the mental health and wellbeing of young people.  As a social design practitioner, Andrew believes in intentionally incorporating positive, practical, and innovative pro-mental wellbeing methodologies into “business as usual” approaches to service and program delivery, creating a social fabric where young people are helped and supported as early as possible, enabling them to go on to lead productive, healthy lives.

Andrew has worked with diverse multicultural and multiethinic communities and values diversity as a community strength, in all its forms.

A third generation Australian, he is from a multicultural family himself and a proud grandchild of “pueblos originarios de chile” (Mapuche peoples of Chile).
