Since 2020, she has been cultivating an olive grove in Puglia using entirely natural methods.
Using the expertise she has learned from local farmers and consolidated through her training at O.N.A.O.O., she covers the entire production chain — from land maintenance and pruning to harvesting, pressing, packaging and exporting — all carried out according to best practices.
In Switzerland, she offers her professional expertise to innovative companies in the olive oil industry, organises tastings and workshops.

She is involved in the fight against Xylella, a devastating disease affecting olive trees (https://www.tvsvizzera.it/tvs/qui-italia/quegli-svizzeri-e-quelle-svizzere-impegnati-nella-lotta-contro-la-xylella/78291581).

Hilda is a certified Professional Olive Oil Taster since 2017 and a student with ONAOO since 2014.

She is a passionate home cook and baker always looking for new ways to use extra virgin olive oil in her kitchen.

Agricultural Engineer, graduate of Ege University Faculty of Agriculture (Dairy Technology), currently engaged in olive cultivation and olive oil production.

I successfully completed the sensory training program at ONAOO and passed the official examination in Imperia, Italy, gaining formal qualification in olive oil sensory analysis in 2025. As olive growing and olive oil production are my profession, I wanted to further develop myself and gain deeper knowledge from one of the world’s leading institutions. My aim is to better understand olive oil, to express it correctly through sensory analysis, and to be able to communicate its true value with accuracy and confidence.

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

As a result of the substantial increase in production, they made the decision to sell their business in the Netherlands. Currently, the company’s exclusive focus is on the production of extra virgin olive oil in Italy under the Di Lorenzetto brand, which is renowned for its superior quality.

To further refine the quality of their oil and gain a deeper understanding of the varieties, flavors, health properties, and defects of olive oil, Diana decided to embark on a training course. 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.
