Kelvin is the Chairman and Co-Founder of the Company.

In 1977, Kelvin began his entrepreneurial journey by starting a cocoa trading business in Bagan Datoh, Perak. Foreseeing the potential of national cocoa production would be centred in Sabah’s east coast, he expanded to Tawau in 1986, pioneering an integrated approach to the cocoa business that combined upstream sourcing with downstream processing.

In the 1990s, Kelvin applied a similar integrated strategy to the oil palm industry by establishing plantations and mills in Sabah. To enhance sustainability, TSH built a biomass cogeneration plant in 2004.  In 2006, the company formed TSH-Wilmar Sdn. Bhd., a downstream palm oil refinery joint venture with Wilmar.

Collaborating with Indonesian entrepreneur Garibaldi Thohir, Kelvin expanded TSH’s operations to Indonesia in 2003. The venture now encompasses 36,000 hectares of oil palm plantations and four mills, establishing TSH as a regional integrated player in the oil palm industry.

TSH was listed on Bursa Malaysia’s Second Board in 1994 and elevated to the Main Board in 2000. He also spearheaded the company’s secondary listing on the Main Board of the Singapore Exchange in September 2023.

Kelvin is committed to environmental conservation. He led a biodiversity conservation program in Sabah’s Meliau Range with the Sabah Forestry Department, and served as a trustee of the Borneo Conservation Trust Sabah from 2010 to 2013.
