Najeeb Yaser
( Palestine )

PROFILO:

Najeeb is a distinguished banking professional whose expertise extends far beyond the financial sector. While he has achieved significant success in his career, his true passion lies in the art and science of olive oil, a pursuit deeply rooted in his family’s heritage and the rich traditions of Palestine.

Motivated by this connection, he embarked on an educational journey at the ONAOO School, concluding in 2024 with the achievement of a professional taster qualification, marking him as the first from Palestine to achieve such recognition. Originating from the historic town of Birzeit, whose name translates to “olive oil well,” Najeeb grew up immersed in the legacy of olive cultivation.

His family co-owns an olive press in northern Palestine, where they blend generations of knowledge with modern, environmentally sustainable practices to produce exceptional olive oil. Najeeb’s journey reflects the deep, enduring relationship between people, the land, and one of its most revered symbols — the olive tree.

Wilma van Grinsven-Padberg

In 2018, Wilma finished her training at the ONAOO. She was in charge of buying Mediterranean products, including olive oil. Being Dutch, she didn’t know much about olive oil and found a school in Italy.

She loved it so much that she left her job and started working in the olive oil business. She also trained as a sommelier in New York and a master miller in Jaen. She asked the Ministry to appoint her as panel leader at the European Union. She wrote the book “Olive Oil,” which has been translated into English, French, and German.

Her book encourages olive oil lovers to meet in Imperia. O.N.A.O. is a big family! He also founded the Olive Oil Institute, which has a panel of fifteen members, most of whom were trained by O.N.A.O.O. The Institute has an electronic nose, so that testing can be done objectively. Some universities are also trying a similar method. This should improve quality overall. But the panel will always exist because human judgment is needed.

Al Kaakour Ibrahim

“Olive oil is not an agricultural trade, it is a product of Love and Faith”.
Born in Baassir (Lebanon), one of the oldest countries to ever produce olive oil in the world, Ibrahim Al Kaakour is continuing an over 300 year old family legacy in the cultivation of olive oil.
Graduate of Electrical and Computer Engineering from the American University of Beirut and a holder of an Executive MBA with a focus on finance from Ésa/ESCP Europe, Ibrahim did not let his daily routine sway him from becoming a professional taster and a master blender/producer of olive oil.
To give homage to both his paternal Lebanese and maternal Greek Heritage, He currently owns two brands that he developed under his company LGOO with a luxury line of exquisite blends of olive oil, honey and many other organic products in state of the art branding.
Ibrahim is also keen on helping the local communities to improve the quality of olive oil and spread not only the know-who that he acquired as an olive oil sommelier, but also the culture, the roots and the love that he shares by hosting tasting sessions and introductory seminars in the olive oil center of the family Villa in the beautiful Mediterranean town of Baassir (a syriac aramian name that translates to “The House of Juice”).
From 2017 he is Member of ONAOO where he started his educational path. On January 2020 he concluded his studies by obtaining the Qualification of Professional Taster of ONAOO.
