From the glamour of Monte-Carlo to the pulse of Singapore, Guillaume Gallas has forged a remarkable path through some of the world’s most iconic cities—leading 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 properties—he’s a transformative leader reshaping the art of hospitality.
As General Manager of Mondrian Singapore Duxton, one of Southeast Asia’s 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 doesn’t just sustain—it elevates, inspires, and sets new benchmarks for the region’s luxury hotel scene.
But Guillaume’s 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 – 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-19—safeguarding 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 Accor’s 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 results—but in relationships, resilience, and the ability to turn vision into reality.
Inspired celebrates Guillaume Gallas for redefining global hospitality through visionary leadership and an unwavering commitment to service and operational excellence.
