CTNS Staff and Associates


As an agency we strive to provide high quality neuropsychological services. In order to achieve this, we contract with psychologists dedicated to client care, personal growth, and developing the field of neuropsychology.

Catherine Govender
Director / Clinical Psychologist

MA Clin Psych (UPret); PhD Psych (UNISA)
HPCSA: PS 0090018 Practice Number:0226173

Catherine Govender is a Clinical psychologist with a special interest in neuropsychology. She has 12 years of experience in neuropsychological assessment and research, as well as  teaching university students about about brain-behaviour relationships.


Catherine works from a systems approach, in order to assist individual clients and their significant others to  understand the impact of atypical brain functioning and/or brain changes. Understanding brain injury does not always bring about change, so her work also focuses on the practical steps needed to participate in activities of daily living for those affected. Additionally she focusses on assisting client's and their families in regulating cognitive and emotional responses, in order to assist you in gaining optimal quality of life.

Peta Wills

Peta Wills is a Clinical Psychologist with a special interest in working with individuals, and their families, who have had a traumatic brain injury, such as a stroke or head injury. Through the process of neuropsychological assessment and transparent feedback, regarding cognitive strengths and weaknesses both the client and family can develop insight.

In regards to psychotherapy Peta predominantly works within a dialectical behaviour therapy framework. She has a special interest in working with individuals who have had a brain injury, as well as other forms of trauma, including acute stress disorder and post-traumatic stress disorder. 

Christopher du Plooy
PS 0150100 Practice Number: 0965685

Christopher is a Neuropsychologist presently working within UCT and CTNS. He is able to provide neuropsychological assessments for those who have experienced (or are experiencing) brain changes and brain-based disorders. This includes diagnoses such as possible stroke, head injury, and other neuro-cognitive disorders. 

Jessica Ringshaw

MA Neuropsychology (UCT)

HPCSA: PS 0146641; Practice number 0945919

Jessica is a Clinical Neuropsychologist with a MA degree from the University of Cape Town. She conducts neuropsychological assessments with both children and adults and has experience working with a broad range of pathologies including neurodevelopmental disorders, epilepsy, traumatic brain injury (TBI), neurodegenerative disease, autoimmune disease, dementia, stroke, and infectious disease.

Jessica specialises in diagnostic assessments, and she uses a hypothetico-deductive approach to develop a comprehensive and valid understanding of neuropsychological syndromes. This involves considering the intricate relationship between a patient’s clinical presentation, the underlying brain pathology, and the associated neurobiological mechanism that links nosology and disease. Jessica takes special care to provide detailed feedback and psychoeducation for her patients and their families, and she works together with them to identify appropriate referral pathways, practical solutions, and compensatory strategies where possible.

Jessica’s primary research interest is in neurodevelopment, and she has special expertise in developmental disorders and paediatric neuroimaging of high-risk infants and children.  Within these fields of research, Jessica’s two specific areas of focus include Autism Spectrum Disorder (ASD) and nutrition, respectively.

Abigail Wilson
Clinical Psychologist

MA Clin Psych (UCT)

Abby is a Clinical Psychologist with a keen interest in adjustment issues and navigating life transitions such as post-operative or medical event, change in career, relationship difficulties, grief and bereavement, as well as body image concerns and the treatment of psychiatric conditions related to medical illness.

A curiosity with how we each come to be the unique person we are informs both Abby’s
psychotherapy practice and personal life. She works from a psychodynamic approach to strengthen the self, increase resilience and actualise one’s potential. In addition, she draws on a range of skills based modalities according to the individual client’s needs.

Gosia Lipinski

MA Neuro Psych (UCT); PhD (UCT)

Gosia is a clinical neuropsychologist and a sleep scientist. She predominantly sees adults who have experienced a brain injury. She has experience working with a very broad range of pathologies including but not limited to stroke, traumatic brain injury, dementias, infectious diseases of the central nervous system, metabolic conditions affecting the brain, cancer, and epilepsy.


In addition to working with adults, she also sees children with brain injuries or neurodevelopmental difficulties. She believes that it is critical for patients and their families to understand their brain injuries to be able to implement practical solutions as well as come to terms with the changes that follow such an injury.

Hetta Gouse

MA Neuro Psych (UCT); PhD (UCT)

Hetta is a clinical neuropsychologist with a special interest in HIV-associated neuro-cognitive disorders, the dementias (e.g. Alzheimer’s disease), traumatic brain injury, and occupational functioning secondary to neurological disorders. In addition to general clinical neuropsychological assessments, she provides psycho-legal assessment for individuals who have experienced traumatic brain injury. Her PhD focused on neuropsychological, behavioural, and functional predictors of outcome in traumatic brain injury in litigants. 


Hetta has been involved in psychological research in local and sub-Saharan African settings for sixteen years. She believes that a holistic understanding of the patient is key to diagnosis. In her approach to neuropsychological evaluation she typically gathers relevant medical and
historical information. This then informs the clinical neuropsychological assessment, followed by analysis and integration of this information, and finally feedback to the patient, their family and the referral source.

Marina Lawrence

MA Neuro Psych (UCT)

Marina completed her masters in Neuropsychology at the University of Cape Town. She conducts neuropsychological assessments with both adults and children suffering from the effects of brain injuries or illnesses (i.e. from developmental abnormalities, stroke, head injury or neurodegeneration). Marina also has an interest in Autism, as this was the focus of her research.


Marina adapts each neuropsychological assessment to best suit the patient's needs, based on the medical and psychiatric history provided. She uses these assessments to assist with diagnoses as well as areas of strength and weakness. Marina tries to involve individuals as well as their families when feeding back information, to ensure that the nature of the neuropsychological difficulties and their effects is better understood.
