From the glamour of Monte-Carlo to the pulse of Singapore, Guillaume Gallas has forged a remarkable path through some of the worldโs most iconic citiesโleading luxury hotels with commercial acumen, creative flair, and an unrelenting focus on operational excellence. With over 25 years in the industry, he is more than a steward of standout propertiesโheโs a transformative leader reshaping the art of hospitality.
As General Manager of Mondrian Singapore Duxton, one of Southeast Asiaโs most buzzworthy lifestyle hotels, Guillaume brings both vision and rigour. Since stepping into the role, he has elevated P&L performance, introduced dynamic pricing strategies, and championed guest-first programming that mirrors the cultural energy of Duxton Hill. His leadership doesnโt just sustainโit elevates, inspires, and sets new benchmarks for the regionโs luxury hotel scene.

But Guillaumeโs journey is far from confined to Singapore. Across London, Hong Kong, Tokyo, Beijing, Dubai, and Oman, he has built high-performing teams, revitalised underperforming assets, and steered properties through high-stakes environments. Whether repositioning F&B at The Mira Hong Kong or launching The Silveri โ MGallery in Hong Kong, Guillaume combines strategic thinking with deep empathy.
During his tenure as Multi-Property General Manager, he led Novotel Citygate to become a top-performing medical hotel at the height of COVID-19โsafeguarding jobs and ensuring service continuity during unprecedented times.

At the core of his leadership is a belief that hospitality begins with people. Teams that feel valued, empowered, and inspired deliver the kind of service that creates lasting impressions. This human-first philosophy has earned him industry recognition, including Accorโs Guest Experience Excellence Award and a place among the Top 100 Inspiring Professionals by Inspired Magazine.
Today, as he shapes the next chapter of Mondrian Singapore Duxton, Guillaume Gallas remains a global hotelier who honours tradition while setting new standards for luxury, growth, and guest experience. His story is a powerful reminder that in hospitality, true leadership is measured not just in resultsโbut in relationships, resilience, and the ability to turn vision into reality.
