Dr Johann Riedemann is a Clinical Radiation and Molecular Oncologist practicing at the Cancercare units in Cape Gate and Panorama. He has extensive experience in paediatric, adolescent and young adult oncology having dedicated his post graduate studies and research to this specialist field.

Crayon is the culmination of his vision to provide the highest quality precision oncology for children, adolescents and young adults in South Africa. The newly established special unit based at the Cape Gate Oncology Centre provides access to advanced radiotherapy techniques, risk-adapted chemotherapy, endocrine, biological and immune-mediated therapies.

His vision includes caring for those fortunate enough to undergo curative treatment, but also for those with incurable disease in need of palliative intervention and/or supportive care.
