Therme Group has announced the appointment of Mr Tan Boon Khai as the Chief Executive Officer for Therme Group Singapore. With more than 30 years of experience in both the public and private sectors in Singapore, Boon Khai will lead the development of Therme Singapore, Asia’s first next-generation urban wellbeing destination at Marina South, as part of Therme Group’s global expansion in the fast-growing wellness space.

Before joining Therme Group, Boon Khai was the Chief Executive Officer of JTC Corporation, where he spearheaded numerous transformations across Singapore’s industrial landscape. Previously, he served as Chief Executive of the Singapore Land Authority, as Senior Vice President at CapitaLand, and as Regional General Manager for Singapore and Malaysia at Ascott Limited, the world’s largest serviced residence operator. A lawyer by training, Boon Khai began his career as a Justice’s Law Clerk and has held various portfolios as a lawyer in the private sector and with the government.

Dr Robert Hanea, Founder and Chief Executive Officer of Therme Group, said, “We warmly welcome Boon Khai as a key member of Therme Group, as we embark on our global expansion, building on the success of Therme’s social wellness infrastructure over the last 15 years. Boon Khai brings with him a proven track record in development, management, and hospitality, and we are delighted that he has joined us in developing the next evolution of Therme’s wellness experience in Singapore, and bringing wellness to all locals and visitors in Singapore and the surrounding region.”

Therme Group’s first destination in the region—a S$1 billion, state‑of‑the‑art wellbeing resort set to open in Singapore in 2030—will be Asia’s first large‑scale social wellbeing development. Situated on a 4-hectare waterfront site next to Marina Barrage and Gardens by the Bay, Therme Singapore is designed as an inclusive destination for all. 

The wellness destination aims to make holistic wellness accessible to everyone while promoting healthy living, social connection, and community vitality. It is expected to attract around 2 million visitors a year when at full operational capacity, with roughly half coming from overseas.

Mr Mah Bow Tan, Chairman of Therme Group Asia, said, “Therme Group’s entry into Singapore marks a significant milestone in realising the vision of Therme Group to make wellness accessible to all. Asia, particularly Singapore, presents great opportunities for Therme Singapore to showcase its wellness concepts and technology. Boon Khai’s leadership track record, deep expertise, and strong stakeholder relationships will be invaluable in ensuring that Therme Singapore becomes an iconic wellness destination in Singapore, enhancing the vibrancy of the new Marina South Coastal area, and delivering on Therme’s vision of Wellness for All.”

“I am honoured to join Therme Group at such an exciting and pivotal moment in its global journey. Singapore is uniquely positioned to become a leading hub for urban wellbeing in Asia, and I look forward to working closely with our partners and stakeholders to bring Therme Singapore’s vision to life—creating a world-class destination that enhances quality of life for both locals and visitors,” said Mr Tan Boon Khai, Chief Executive Officer, Therme Group Singapore.
