Kerzner International has announced the appointment of Jules Dubois as General Manager of One&Only Mandarina, on the Riviera Nayarit, Mexico. The French-Spanish-English-speaking executive took up his post in August, following a career of more than eighteen years built within premium establishments.
His appointment also marks a return to the One&Only brand, which he left in 2023 after a stint at One&Only Palmilla, in Los Cabos.
A Career Built Across Europe, Asia and the Middle East
A graduate of Vatel France in hotel management (2005–2008), Jules Dubois began his career at Mandarin Oriental in London before taking on roles supervising banquet operations, then as assistant director of food and beverage in Paris. He went on to join Ritz-Carlton in Tokyo, where he headed the property’s restaurants, before returning to Mandarin Oriental in Hong Kong and Bangkok as assistant director of food and beverage.
Between 2019 and 2021, he took charge of food and beverage at the Burj Al Arab in Dubai, overseeing annual revenue of $60 million, in a context marked by workforce reductions and the onset of the Covid-19 pandemic. He then joined One&Only Palmilla, in Los Cabos, as Director of Food and Beverage, where he oversaw nine outlets and two restaurants helmed by chef Jean-Georges Vongerichten, generating F&B revenue of $28 million.
A Brand Transition Led in Dubai, Followed by Operational Leadership at The St. Regis Mexico City
In 2023, he joined Caesars Palace Dubai as Hotel Manager, where he oversaw the property’s transition to the Banyan Tree and Delano brands following the withdrawal of the Caesars licence. There, he was responsible for a $125 million budget and managed 800 employees, while maintaining the resort’s Forbes Five-Star status throughout the transformation.
From April 2024 to August 2026, he served as Hotel Manager of The St. Regis Mexico City, where he ensured the property’s full operational and commercial performance, with responsibility for the Rooms, F&B, Spa, IT and guest experience departments. There, he drove revenue growth and maintained Forbes Five-Star standards during an active hotel renovation.
Governance and Priorities at the Helm of Mandarina
According to information provided by Kerzner International, Jules Dubois will be responsible for leading the resort in creating experiences that invite guests to relax, recharge and reconnect with nature, in line with the One&Only brand positioning. No successor to his previous position has been announced by Kerzner International at this stage.
