Richard Kuppusamy

President

If we want change (to make Singapore more inclusive), we need to be active participants in that change. No one else is going to do it for us.

Richard Kuppusamy has been serving as the President of DPA since September 2017. When he is not heading the Lendlease Digital office or supporting DPA’s board of directors, Richard spends his time on Netflix, gaming and building mechanical keyboards. One of his goals is to champion the needs of people with disability in Singapore. Inclusion to him means no one gets left behind, where everyone has the equal right to live, work, play and do so safely and without judgement or discrimination.

I wanted to be part of a movement which will be a voice for those with invisible special needs.

Peggy Sarah Yee has been practising law for 34 years and is particularly interested in Family Law matters. She is deeply passionate about advancing the cause of those with disabilities, especially invisible disabilities. A foodie at heart, Peggy is always on a hunt for good food and is also an avid cook who loves experimenting with new recipes in her home kitchen.

Chang-Tang Siew Ngoh

Honorary Secretary

Inclusion to me is helping to ensure no one is left out by virtue of their (dis)abilities, ethnicity, religion or socio-economic status. In the disability sector, that means removing any disabling barriers around having a disability.

Chang-Tang Siew Ngoh has served on DPA’s Board since 1993 in various capacities. Currently retired, Siew Ngoh had years of working experience in personnel management, research and planning on three statutory boards. She has also taught at several tertiary institutions as a tutor and adjunct lecturer while serving on the Executive Council of the Singapore Association for the Deaf (SADeaf). She enjoys taking walks in the park and listening to evergreens.

Navin Nair

Honorary Treasurer

Being a person with disability, I am passionate about advocacy works and my ultimate goal is to keep making a better version of myself and always live life to the fullest.

Dr Navin Nair holds a DBA (Doctorate) Degree in Managerial Science from USA, Masters in Human Resource Management from USA & UK. Learning is his passion and he enjoys life to the fullest and upholds the motto “equal rights and opportunities” for all. Playing the piano and keyboard relaxes him and he rarely says no to briyani and awesome desserts.

Mike Chin

Assistant Honorary Treasurer​

There is so much to be done in Singapore for us to be considered an inclusive society.

Mike Chin is always on the go. He is a positive thinker who would love to learn to play the piano someday. Inclusion to him means having the freedom to go about your day, not worrying about being judged by the way you look, talk and walk. Mike has always been interested in history. Stories of how people lived across different eras are of particular interest to him. Despite having a sweet tooth, Mike is trying to give up sugary desserts to pursue a healthier life.

Dawn-Joy Leong

Committee Member

It is not my purpose to “fix” what is “broken” but to empower beauty in the vulnerable and unnoticed.

Dr Dawn-Joy Leong is an Autism researcher and multi-disciplinary artist. She loves spending her time with the love of her life, Lucy Like-a-Charm and knitting sweaters for skinny dogs. Lucy Like-a-Charm, a rescued former racing Greyhound is Dawn-Joy’s retired assistance dog, creative muse and closest companion.

Cassandra Chiu

I’m a strong advocate for people with disabilities and feel very strongly about equal opportunities for the disabled and Guide Dogs. I dream that one day my beloved Singapore has a place for each and every one of us.

Cassandra Chiu provides therapy to clients struggling with mental health difficulties. When she is not counselling, she is found hanging out on the floor with her guide dog or putting together a beautiful meal for her family and friends. Cassandra wears her advocacy on her sleeve and is on a mission to create a kinder place for future generations of people with disabilities in Singapore.

We have a lot to share and offer to the community, from how we view situations to how we deal with obstacles in our way. While we are different in some ways, there is much we can all learn from one another.

He was diagnosed in his mid-thirties with ADHD, Autism and Tourette’s Syndrome and uses his life lessons to advocate inclusive hiring and learning agility in organisations.

We are different in many ways, but ultimately, we’re more alike than we are different. Because we’re all human beings.

Alvan was a former staff of DPA handling the advocacy portfolio. He has since moved on and is currently serving as Deputy Director with Singapore Association for the Deaf. Alvan believes in having a larger disability community coming together with similar experiences and purpose; strength in numbers.

I see the stigma surrounding persons with disabilities and the challenges organisations that represent persons with disabilities face. I believe having a cohesive brand strategy can help address this stigma, and enable the DPA to achieve our vision.

Arsalan is a brand strategist with over twenty years of experience working in Singapore and the US. He has a genuine love for brands and how consumers connect with and form opinions about the brands they use. Arsalan has been serving as an Advisor of the board since 2010.
