Dimo is regarded as one of the finest pastry chefs in South Africa. His formal training began with the City and Guilds pastry course and continued in the United States, France and Switzerland. After his formal training, Dimo helped establish many pastry brigades in five-star hotels in South Africa - he was, for example, the Head Pastry Chef at the One & Only in Cape Town.

Dimo has also worked and competed as a pastry chef internationally. He represented South Africa in the United States Culinary Classic Competition, at the Culinary Olympics in Germany and at the Culinary Challenge in Singapore. However, he never forgets that his love affair with chocolate began at a young age tasting confectionery at a local confectionery shop in Johannesburg.
