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.

Murat Faik Ünver, of Swiss and Turkish descent, was born and raised in Geneva, Switzerland. From a young age, he developed a deep interest in culinary arts and cooking. To pursue this passion, he studied Applied Sciences in Hospitality Management and Business Administration at Glion Hospitality School in Montreux.

After completing his university studies, he worked in the hospitality industry for a time, but he soon realized his true calling was to produce something from the land and engage in agriculture. To fulfill his aspirations, Murat returned to his roots in Turkey, where he planted approximately 3,000 olive trees and began cultivating his family’s land. Additionally, he acquired an abandoned olive oil factory, marking the beginning of his brand, Olivya Gökçeovacık. Since 2019, Murat and his team have been producing their own high-quality olive oil, supplying it locally to those who seek premium olive oil.

Over the years, they have garnered multiple awards, creating many moments of pride. Driven by his passion for creating and producing, Murat’s pursuit of becoming a certified olive oil sommelier will further enhance his expertise and enable him to continue excelling in his field.

Born in a country where butter is king and mayonnaise is queen, I was pleasantly surprised by the magnificent taste and pleasantness of extra virgin olive oil during my holidays in south east Crete in the 80s.

At the time, I was working in the product engineering sector in a multinational company, but I was ready for a change.

I started importing this delicious product and I set myself the challenge of letting the people who love butter in my country taste this gift of nature. As a pilot, I knew it was possible to fly without an engine, but not without knowledge and skills. I quickly realized that additional support was needed to achieve my goals.

So I knocked on ONAOO’s door. Thanks to the dedication of the teachers, I embarked on a fascinating 3-year learning path.

I enjoyed developing my skills and knowledge and thanks to this support I have seen my business grow. Through retail, restaurant, direct sales and the web shop, I distribute two superb brands of extra-virgin olive oil, one Greek and one Spanish. “Olijfwinkel.be” is my starting point, alongside my company “Techtel.be”.

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.
