Career
Geoffrey began his career as a lawyer, but soon turned to banking in South Africa.
In 1980, Geoffrey was among the founding directors of Rand Merchant Bank with GT Ferreira, Laurie Dippenaar and Paul Harris. He served here as executive director for seven years.
Anglo Suisse Investments Holdings
The financial sector continued to be his main focus of attention after immigrating to the UK in 1987 – there establishing two stock-broking firms, and later founding, together with his twin brother Douglas, an investment company, Anglo Suisse Investments Holdings that concentrated on manufacturing in South Africa, the UK and Australia. In South Africa their activities were conducted through Lenco Holding Limited which was engaged in the manufacture of blow moulding PVC and plastic containers and injection-moulded caps for the packaging industry and also produced foamed styrene trays for the food industry and PVC cling film. One of Anglo Suisse's main UK companies was Sharp Interpack, a company in which Geoffrey invested heavily, and one of the first food-packaging companies in the UK to make extensive use of recycled materials – so successfully that in 2009, at the prestigious Best Factory Awards ceremony it received the top award for its commitment to health, safety and the environment. Demonstrating that environmentalism can be compatible with business success, Sharp captured more than 60% of the UK's packaging market by 2010. In 2010 Sharp was sold for an undisclosed amount to Groupe Guillin
