Our Associates
In July 2018, HOI adopted a new business model based on the Associate/Affiliate Model for delivering management consultancies. In addition to our core group of consultants, we have built an extensive network of senior, highly experienced, independent consultants we can draw upon to staff projects.
We have close working relationships with all Associates and Affiliates from a wide range of relevant academic and professional backgrounds (e.g. medicine, nursing, allied health, public health, statistics, economics, mathematics, psychology, law) who provide specialist input across health, disability, community and social services, ageing and aged care, and mental health sectors. Where we intend to include Associates for a specific project, we clearly identify the Associate(s) proposed, the extent of their participation, and the expertise they provide within the proposal we submit.
