The Sustainable Hospitality Alliance, the leading global network in responsible hospitality, has appointed Glenn Mandziuk as their new CEO.

An internationally recognised chief executive with over 25 years of leadership experience advancing sustainable practices in tourism and hospitality, Glenn has an extensive record of establishing strategies and programmes that inspire responsible growth.

Glenn brings to the sustainability charity his experience engaging with all levels of industry and government on social, environmental and business issues, most recently as President and Chief Executive Officer of Canada’s Thompson Okanagan Tourism Association (TOTA), with its 4,000 industry stakeholders. Glenn’s leadership, together with a motivated team, resulted in TOTA being recognised as a global champion of excellence and innovation in sustainable destination management and responsible industry development practices. In a first in the Americas, TOTA received the Responsible Tourism Institute’s Biosphere Gold Certification, in addition to the UNWTO Quest Certification for excellence in leadership, execution and governance capacities – only the third such recognition for a destination management organisation in the world.

Glenn is currently a director on the Board of the Global Sustainable Tourism Council and the Responsible Tourism Institute, and has advocated for sustainable destination management practices in nearly 20 countries covering six continents. He also has 10 years’ experience in the hospitality industry in family-owned and operated hotels and resorts, and holds a Master of Environmental Design degree majoring in sustainable tourism planning.

Wolfgang M. Neumann, Chair of the Sustainable Hospitality Alliance, said: “While the external environment remains challenging for the industry, the opportunities and urgency of the need to take significant and rapid steps to advance sustainable development globally have never been higher. The Alliance, and our work, has generated enormous momentum across the social and environmental agendas in recent years, and we are highly confident that Glenn is the executive to lead our organisation into its next phase of growth and influence.”

Glenn Mandziuk, incoming CEO of the Sustainable Hospitality Alliance, said: “As a passionate believer that tourism can be an agent of positive change, I am extremely honoured and enthused to be joining the Sustainable Hospitality Alliance team. I am very excited to bring the organisation’s vision to life and build on their strong momentum. I admire all those involved over the years for having the foresight to establish such a pivotal organisation that is crucially positioned to inspire the industry as it reimagines itself post-pandemic.”

Glenn replaces the charity’s previous CEO, Madhu Rajesh, who left the organisation in September 2021 after guiding it to a solid position as an established independent charity with members comprising 30% of the global hotel industry by rooms including 15 world-leading hotel companies. Patrick O’Meara has continued her committed leadership as Interim CEO, and will manage the transition until Glenn’s official arrival in April 2022.
