Our Board of Directors
Chairman
Dr Christopher Lien
Dr Christopher Lien is a Senior Consultant in Geriatric Medicine at Changi General Hospital and has led Community Geriatrics since 2006. Over the course of his career, he has worked across healthcare and community care, with a focus on helping older adults receive the right support not only in hospitals, but also in the places they call home.
Christopher has seen first-hand that caring for older adults is about more than medical needs. Family, friendships, social connections and a sense of belonging can be just as important in helping someone age well. These experiences have shaped his approach to care and his belief in looking at the whole person, rather than simply the illness.
He enjoys the idea of bringing generations closer together, giving young people the opportunity to learn from older adults while creating companionship and support for those who may otherwise feel alone. At TriGen, Christopher brings his experience in geriatric medicine and community care to help create a more connected approach to ageing, where healthcare and human connection go hand in hand.

Dr Kennedy Ng Yao Yi
Dr Kennedy Ng is a Medical Oncologist at the National Cancer Centre Singapore and Clinical Director in the Division of Population Health and Integrated Care at Singapore General Hospital. His work spans clinical medicine, healthcare systems, health policy and service design, with a focus on making healthcare more accessible and responsive to the needs of different communities.
For Kennedy, TriGen grew from a simple belief that caring for older adults should never be limited to what happens within the healthcare system. As a medical student, he saw how much a person's experience of ageing and illness could be shaped by the people around them — by whether there was someone to check in, lend a hand, or simply be there. Together with his co-founders, he wanted to create that sense of connection for more older adults, while giving younger people the opportunity to be part of it too.
More than a decade on, Kennedy continues to find meaning in the relationships that have grown from that idea. He values the moments when a young volunteer and an older adult begin as strangers and, over time, become familiar faces in each other's lives. For him, this is what makes intergenerational care so meaningful: it is not only about what one generation can give another, but about what we discover, learn and share when we make space for one another.
Audit
Mr Tham Tuck Seng
Mr Tham Tuck Seng has more than 30 years of experience in professional services, with a career spanning assurance, corporate finance, capital markets, accounting and governance. During his time with PwC Singapore, he served as Partner and Capital Markets Leader, advising companies across Singapore and the region on listings, capital market transactions and growth. He has also held leadership positions within the professional and corporate sectors, including as Chairman of the Institute of Singapore Chartered Accountants' Corporate Finance Committee.
Tuck Seng's connection to community care comes from something much closer to home. Caring for his ageing mother gave him a personal understanding of the joys and challenges that come with supporting an older family member. It also made him think about how we can create communities where older adults and their families feel less alone in navigating the journey of ageing.
He is drawn to the way intergenerational programmes can create meaningful connections between people of different ages. He believes young people have much to learn from older generations, just as older adults can benefit from the energy, companionship and perspective that younger people bring. At TriGen, Tuck Seng contributes his experience in governance and financial stewardship while helping the organisation grow sustainably and create more opportunities for generations to connect.
