Dr Beretta completed her undergraduate studies at Wits University. During her community service assignment to paediatric surgery, she discovered her passion of working with children. She conducted her specialty and completed her MMED through Wits University and was then presented with the opportunity of sub-specialising through Wits Donald Gordon Medical Centre. She completed her training in 2018 and is currently heading up the Paediatric Liver Transplant Unit at Wits Donald Gordon, the largest paediatric liver transplant unit in South Africa.

Her aspirations are to improve awareness and access to liver transplantation in South Africa, raise awareness of cholestatic liver disease and acute liver failure and act as an ambassador for South Africa in the international paediatric liver transplant community. Her efforts to represent the South Africa experience include engaging in multiple international studies including the Global Alagille Alliance, Severe Hepatitis in Paediatric Patients (SHIPP) and the Portal vein Obstruction Revascularisation Therapy After Liver transplantation (PORTAL) studies. Her hope is to highlight South African paediatric liver transplant patients as an important demographic that merits increased awareness and consideration in the global arena.
