Simon Monro Grier: Studied at Stellenbosch University but he was more interested in the outdoors, dovetailing perfectly with Jeff who was more interested in the cellar. Simon is responsible for the vineyards at Villiera and he has become a recognized authority in environmental aspects.
Cathy (nee Grier) Brewer CWM: Studied computer science at UCT. After the family purchased Villiera wines she opted for a career change and went to study at Prue Leiths school of Food & Wine in London. She joined Villiera in 1987 and currently heads up the sales and marketing departments. She is also a Cape Wine Master.
Alexander Monro Grier: Studied BSC Food Science at Stellenbosch University.
