About AMEN Australia


The Australian chapter of the Adventist Medical Evangelism Network (AMEN) was formed by a group of doctors, dentists, medical and dental students who felt the need to experience a personal revival of medical evangelism in life and practice, and were inspired by the vision and mission of AMEN in the US.

It all began when a few like-minded attendees at an AYC convention in Sydney in 2010 met over lunch discussing ways of improved networking to support and encourage one another. The following year, in April 2011, contact was made with AMEN in the US to enquire about resources for forming an Australian chapter, which was met with favourable and most encouraging support. In August 2011, at the Adventist Health Professionals’ Conference at the Sydney Adventist Hospital, a group of attendees interested in the formation of this chapter met over an evening meal. Out of this meeting stemmed a vision for a formal conference, and a group of like minded health professionals collaborated to arrange the inaugural AMEN Australia conference in Melbourne, December 2012. From this inspirational conference with certain evidence of God’s blessing, a formal board was elected and AMEN Australia was born.

Our mission and objectives remain similar to the parent organisation, and we are grateful for the support and encouragement we have received from the Adventist Health Department in our Division; we look forward to working together collaboratively to see the fulfilment of our shared vision.

The Lord’s blessing on AMEN globally is being manifested in the following tangible ways:

  • AMEN members continue to be involved in overseas mission work in many places.

  • AMEN journal, “The Medical Evangelist” continues to provide practical, potent reports of medical evangelism from the field.

  • A group of AMEN members in the US launched Life and Health Network – a cutting-edge, internet-based television network which broadcasts the best of Adventist health programming 24/7.

  • AMEN’s international influence is growing – originally in the US (see for details), it now includes chapters in Nigeria and the UK as well as Australia.

  • Despite its growth and development, AMEN remains dedicated to its original goals – to inspire, equip, and motivate health professionals to become effective medical evangelists at home, in the clinic, and in the community.
