The Mérida State Symphony Orchestra (Spanish: Orquesta Sinfónica del Estado Mérida or OSEM) is a symphony orchestra based in the Venezuelan city of Mérida.
From 2005 to 2007, working on behalf of the Kibbutz Lohamei HaGeta'ot, Yogev led partnership negotiations between Osem and Tivol, as well as the sale of the kibbutz's stake to Nestlé.
A significant accomplishment of the OSEM, assisted by the Trust Foundation, has been the institutionalization of the Festival Valle de Bravo year after year, since 1997.
