PROFILO:

Born in Istanbul and graduated from Boğaziçi University in 2008. My journey in olive oil sector began during my professional career as a Brand Manager at one of Türkiye’s most established and respected olive oil brands. What started as a professional responsibility quickly transformed into a deep personal passion for olive oil and its cultural significance. This long-term professional exposure and knowledge of the entire value chain combined with a growing personal dedication to learning and tasting, ultimately led me to pursue formal training and certification with ONAOO.

I am currently working as a brand consultant mainly working with olive oil brands. Besides, I am olive oil panel member of Ayvalık Chamber of Commerce.
