Diana Coolegem
( Holland )

PROFILO:

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.

After having her first baby in 2016, she replaced her high heels with Hunter boots and purchased a small farm in Italy to become an olive grower. Now she imports her family’s extra virgin olive oil to Estonia: CASA FONTESTATE. Every bottled harvest has a new label design from one of Estonia’s famous artists, which makes it a unique and memorable shopping experience every year.

She is a Professional Taster certified by ONAOO; in London she completed a Program to become an Olive Oil Sommelier.

Mokdad Saad

I began my technical course at ONAOO in September 2022, building a strong foundation in extra virgin olive oil quality standards, and evaluation. In February 2023, I started the ONAOO Professional Tasting Course, further developing my sensory analysis skills and ability to assess EVOO based on official tasting methods. I completed my ONAOO course in November 2025.

Extra virgin olive oil is more than a product to me, it is a symbol of history, culture, and tradition that has been valued for thousands of years across the Mediterranean. From ancient civilizations that used olive oil for food, health, and daily life, to modern producers who preserve traditional methods while improving quality standards, olive oil has always represented purity, resilience, and connection to the land and people.

I am proud to be part of this long heritage by sourcing only exceptional EVOO and promoting oils that are authentic, fresh, and truly representative of their origin. I am committed to continuous learning and to maintaining the highest standards in quality, traceability, and transparency, so customers can experience olive oil the way it was meant to be fresh, healthy, and deeply rooted in history.
