Kostas Maselis

Kostas Maselis is the founder of MasWorth, a company dedicated to sourcing, producing, and promoting exceptional Greek extra virgin olive oil and olive-derived wellness products. Through MasWorth, he has developed a portfolio of premium brands that are increasingly recognised by consumers for their quality, authenticity, and nutritional value, including MasWorth EVOO, November Olive Oil, and November Polyphenols.

Born into a family of olive oil producers in Greece, Kostas represents the fourth generation of olive farmers and olive oil makers. His family's connection to the olive tree spans generations, combining traditional cultivation methods with an unwavering commitment to quality, sustainability, and excellence.

Before establishing MasWorth, Kostas spent many years building a successful career in finance, investments, and corporate leadership, working with large international organisations. While these experiences shaped his commercial and strategic expertise, his passion remained rooted in his family's agricultural heritage and the extraordinary potential of premium Greek olive oil.

Driven by a desire to preserve and elevate that legacy, Kostas returned to his roots and founded MasWorth to bring authentic, high-quality Greek olive oil to discerning consumers in the UK and beyond. Under his leadership, the company's products have earned international recognition through respected industry awards and, more importantly, the loyalty and trust of knowledgeable customers who value exceptional quality, authenticity, and transparency.
