With more than two decades of experience spanning luxury and upscale hospitality, Mary Killiny has established herself as one of the Middle East’s most accomplished front office and guest services leaders.

Having held senior leadership positions with Radisson Hotel Group, Marriott International, Wyndham Hotels & Resorts, Accor, St. Regis, Fairmont, Dusit Hotels, and Hilton, she has consistently delivered measurable improvements in guest satisfaction, revenue performance, operational excellence, and team engagement across internationally recognised hospitality brands.
Most recently, Mary served as Director of Guest Services at Radisson Hotel Group in the United Arab Emirates, where she oversaw guest operations for a 288-room hotel featuring 15 food and beverage outlets and a full-service spa. She led multidisciplinary teams across guest services while balancing operational excellence with commercial performance. During her tenure, direct and walk-in occupancy increased by 9 percent through targeted booking strategies, recreation revenue grew by 27 percent year-on-year, operating costs were reduced by 7 percent through sustainability initiatives, and guest satisfaction scores improved by 9 percent following service optimisation and focused employee development.
Under her leadership, the property achieved a record 97 percent Quality Assurance Audit score, the highest in Radisson’s history at the time. The hotel’s Booking.com rating improved from 8.3 to 8.5, while its TripAdvisor ranking climbed from 230 to 130 within a single year. Mary also established a structured upselling programme that earned recognition from FPG and TSA for its commercial impact. The initiative was subsequently adopted across both the Radisson and Wyndham clusters, contributing to improvements in average daily rate, Rooms RevPAR, and overall revenue performance.

Managing large-scale system migrations, operational integration, and brand implementation, she ensured a seamless transition while maintaining operational continuity and guest satisfaction throughout the process.
