About Me

Born in South Africa where I completed my undergraduate degree in Psychology, I have also lived in New Zealand for 10 years before moving to Australia in 2008. My post-graduate Masters and PhD studies in Psychology focused on couples' relationships, conflict and attachment.

I currently predominantly wear two work 'hats'. Most of my time is spent in private practice - I am a Registered Counsellor and specialise in working with couples using primarily the Gottman Method in my private practice.  I also am a Clinical Supervisor for clinicians with a particular focus on relationships/couples cases and building private practice. For more information or to enquire about my availability, please click on the link to my practice website:

or read my couples counselling blog.


I also do some occasional academic writing/work as Adjunct Associate Professor at Victoria University. I have extensive experience as a researcher with strong skills in managing complex multi-site research projects and clinical trials. My area of focus has been broadly in mental health and medical research, including managing a clinical cardiac registry, and more recently university student wellbeing.


My research experience extends to relationship-building, leading teams and strategically interfacing with a wide range of people from cardiac surgeons to construction workers and young people. I am well versed in mixed methods research, evidence reviews and program evaluation. I am dedicated to research excellence, including consumer engagement, adhering to ethical standards, effective resource management and translating evidence-based findings to policy and practice.
