Dr David Horgan (now retired) was recently a Clinical Associate Professor at the University of Melbourne, with high ratings for his lectures to medical students, to other psychiatrists, and to Healthed audiences. He was known as a “last resort” psychiatrist treating depression and high suicide risk. He remains heavily involved in a charity which he founded, the Australian Suicide Prevention Foundation. He initiated the award-winning App “Prevent A Suicide: What to Say” to empower family, friends and colleagues when a person mentions wishing to be dead. He is keen to teach highly practical clinical tips in suicide prevention and he is no longer registered as a practising psychiatrist.
