Nick van den Berg

Organization /  Marble mosaics

Nick van den Berg, director/owner of Miniati, first came to Greece in 1974. Long summer holidays were spent there for a number of years and in 1980 Nick settled in Athens and opened café Witofski, one of the first new style grand-cafés, with a Dutch and two Greek partners. In 1986 he began his designstudio on Miniati street in Athens, where he initially mainly concerned himself with interior design and the manufacture and sale of furniture, lighting and interior design projects. Later the activities expanded especially in the marble sector. (See About Miniati). The many trips with clients to Greece led to new activities such as the organization of a study for the Dutch Quarrymen Bond and the production of a corporate video about marble and eventually resulted in the establishment of Vivari Sculpture. The first sculpture holiday took place in 1996 and was followed by many other workshop tours with themes such as mosaic, philosophy, painting, creative writing, photography and cooking. Nick himself is an enthusiastic amateur sculptor.
