Dr Daniel Brown
Hi, I'm Daniel (he/him).
I'm a Clinical Psychologist with a PhD focusing on the area of health psychology/behavioural medicine.

I currently run a private practice in Brisbane and have a particular interest in working with people with regard to relational and attachment problems.

I work from a relational/dynamic framework and love engaging with clients on their personalised therapeutic journey.

I also love whippets, navel-gazing, and buying books I'll never get around to reading.

Dr Graham du Plessis
With over 15 years of experience as a practicing clinical psychologist, my journey has traversed a variety of settings, including private practice, management consulting, public and private hospitals, NGOs, corrections, defense, police, primary and secondary education, and universities.

I've been actively involved in academia at the University of Johannesburg, the University of Queensland, and the University of Southern Queensland. A strong advocate for evidence-based interventions and best practices, I've emphasized these principles in both my academic and practical endeavors.

My extensive experience extends to training clinical psychology students and interns, as well as contributing to the management of clinical training and services. I bring a passion for fostering the next generation of clinical psychologists and contributing to the advancement of the field.

Student Representative

Mrs Cindy Atkinson
I have always had a strong interest in the welfare of others. I originally started out as a primary school teacher with the intention of becoming a guidance counsellor. After taking some time out to raise my family I realised that my interests extended beyond the school system and I started my journey to become a psychologist. I am currently completing my honours program at UniSQ, after which I look forward to pursuing a Masters in Clinical Psychology. I have a particular interest in children and adolescents, trauma, and women's health.
