The Dionyssomarble Co. S.A. company was founded by the brothers Leontios and Ioannis Argiroudis in 1949 for the commercial exploitation of the white marble deposits in Dionyssos, Attica. Since then, in addition to marble block quarrying and trading, the company has developed numerous other activities through the vertical expansion of operations in Dionyssos and the production of other related building materials. The company has also expanded its activities through the opening and exploitation of additional marble deposits.
