Philippe Bruyninckx

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. “” is my starting point, alongside my company “”.
