In 2019, Diana and her husband initiated the establishment of a modest olive grove in the Marche region of Italy.

She began with a tasting course in Madrid, followed by a technical course and an advanced one at O.N.A.O.O., concluding her studies in november 2024 with the qualification of Professional Taster. In 2024, she also obtained her olive oil sommelier certification at the International Culinary Institute in New York.

Since 2019, Diana has been a member of the Olive Oil Institute panel from the Netherlands. She also regularly conducts workshops and masterclasses for schools, chefs, amateur cooks, and olive oil enthusiasts in the Netherlands and Italy.
