Sonia Ayadi, 39, came to Buffalo from Tunisia with her husband in 2000 to attend D’Youville College where she earned a master’s degree in international business. But before she launched her business career she began a family with her husband Haithen Ben Jaballah, who is also from Tunisia. Their two sons are ages 8 and 11.

In 2008 Ayadi opened Trimex Global, an international trade company that imported olive oil from Tunisia. She started her olive oil boutique in 2012. Zetouna, located on Elmwood Avenue, is the Tunisian word for “olive.” In Tunisia, Ayadi said, olive oil is served by the bowl with lunch and dinner.

People Talk: Would you call yourself an adventurer?

Sonia Ayadi: I am, but at first it was very, very hard to adjust, to learn the language. Because when I first came here I didn’t know any English. I learned in three months. I came here in August, had some fun and then I started school in January 2001.

PT: How did you discover olive oil?

SA: It seemed like a natural idea to me because Tunisia is the second producer of olive oil after the European union: Spain, Italy and Greece. I love olive oil. My husband’s family owns orchards of olive trees. I’m Mediterranean. Our diet is based on olive oil. Everything we do is olive oil. In Tunisia, people don’t buy a bottle of olive oil they buy a lot because they buy for a whole year. In 2010 I had my first shipments and I was selling through Premier Gourmet and Lexington Co-op. In 2012 I resigned from the company and opened my shop to sell my own olive oil.

PT: How did you come upon your company name, Trimex Global?

SA: The TR is trade. IM is import and EX is export. I tried the export first. It didn’t work well. I exported mosquito traps for big areas like one acre. Tunisia has a big tourism industry, but it has a lot of mosquitoes. I was looking for something to clean the area because every time we go for vacation we suffer from mosquitoes. So I found the company and I started to export and at first it worked well, but customer testing took a long time. In the meantime, I was thinking about import.
