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.
