Walker Psychology & Consulting Limited provides mental health services to government, non-government agencies and to the community in the areas of suicide prevention and postvention. We also have over 25 years of experience working with primary care and specifically developing primary mental health care systems both in the US and in New Zealand. One of our key service delivery areas is the training and equipping of people to deal with the issue of suicide at a level appropriate to their situation, e.g., family member, counsellor, psychologist, GP, etc. Walker Psychology has worked to develop an integrated, evidenced-based, multi-tiered system that delivers suicide prevention training at the level appropriate to the person taking the course, that is readily and easily accessible and that is relevant to us in New Zealand.
