Garret Barnwell is a registered clinical psychologist (HPCSA: PS0128317), consultant and independent researcher practicing from Johannesburg, South Africa. 

I practice as a clinical psychologist, and also work predominantly from this perspective in my other areas of work.

I currently run a small private practice from Parktown North in Johannesburg and enjoy focussing my energy on tailoring the therapeutic process to clients that I see. For more information, see Psychotherapy

I hold Masters degrees in Clinical Psychology (cum laude) and Conflict Transformation and Management from Nelson Mandela University, as well as a Diploma in Humanitarian Assistance through Liverpool School of Tropical Medecine (LSTM) and a Certificate in Ecopsychology from the Retreat at Pacifica University, California.

Prior to private practice, I have worked in both inpatient and outpatient settings in the public sector (Graaff-Reinett Community Health Centre, Livingstone Hospital, Elizabeth Donkin Hospital, Chris Hani Baragwanath Academic Hospital).

In practice, I utilise a person’s personal strengths to overcome challenges. This therapeutic style affirms the inherent value of each individual. I provide short-term and long-term psychotherapy. I have a warm approach, and therapy offers a space that is non-judgmental and confidential, where you can be yourself.

Beyond my clinical experience, I have governance- and executive-level experience. This includes being the former Deputy Head of Mission for Doctors Without Borders/Medecins Sans Frontieres (MSF) in South Africa, as well as the former President of MSF in Southern Africa. Core activities included: emergency assessment, project planning and implementation; research and advocacy; advisory and oversight functions.

One of the areas that I previously worked was with mine-affected communities in Rustenburg. During this time, I became attuned to how social ecologies impact on mental health and since then, I have focussed my efforts towards supporting those working on issues of environmental justice. These projects are diverse and include group processes, ecopsychology retreats, writing, research and participatory assessments for community-based action. This energy has also translated into my academic focus. Since 2019, I received a South African Medical Research Council Scholarship for a doctoral study on the psychological responses of individuals and communities to environmental degradation in South Africa. I am in the process of writing this up.

I selectively take on consultancies and draw on my clinical, advocacy and organisational experience. Of these have included leading a vision process for MSF in Southern Africa and developing standard operational procedures for NACOSA’s (Networking HIV and AIDS Community of South Africa) sexual and gender-based violence projects in collaboration with the Psychology Society of South Africa (PsySSA).

I have a warm approach and enjoy co-creating processes, spaces and projects with people. If this style resonates with you, please don’t hesitate to contact me.
