"To protect both customers and staff of the bank, it is crucial to be forward-looking to identify potential and emerging risks that would threaten the security of the banking system."


​John is a Singaporean by birth.  John is married and has 3 grown children. After graduating from junior college, John was enlisted into National Service where he received a local training award and studied at the National University of Singapore.  He graduated with a bachelor's degree in mechanical engineering.  Following his graduation, John then served in the SAF holding various command and staff appointments.  After leaving regular service, John continued to serve as an operationally ready national serviceman and retired from service with the rank of Colonel.

After leaving the SAF in 1994, he joined the then statutory board CISCO as a security consultant. He was subsequently promoted to the position of Director of Security Consultancy.  In this role he was heavily involved in the assessment, planning and design of physical security for many key installations and government offices and buildings.  He also volunteered his time in the National Crime Prevention Council.

His career took him into the private sector when he was recruited by Citigroup as the
Country Manager of Physical Security for Singapore in 2004.  He was promoted to the role of Regional Director of Security for Asia Pacific in 2005.   In this role he laid the foundations and built the security organisation across the Asia Pacific Region.  As the Regional Director in Citigroup, John recounts that the greatest stress was dealing with emergency situations that threatened the lives and safety of colleagues and customers.   These same events were also very rewarding as thankfully, no one was lost under his watch.

John is currently the Head of Group Corporate Security at OCBC. He was recruited to form this new organisation within OCBC in 2012.  Under his portfolio, John is responsible for Business Continuity Management, Physical Security Risk Management, Fraud Risk Management, Security Intelligence and Global Incident Management Centre and Email Content Monitoring. 

More recently at OCBC, John competency was demonstrated though the various initiatives to further be vigilant and prevention of fraud targeting the Bank's customers, and the public.  Through his leadership the Bank also developed an active program to help protect customers to the threat of scams.  This included both internal, industry and public wide educational initiatives such as an OCBC public message service campaign in 2018 across radio, print and social media platforms. Beyond awareness, OCBC is also actively promoting industry wide collaboration to respond to fraud incidents and internal campaign for front-liners to identify customers who may be potential victims of fraud.  These helped prevent customers from becoming victims of scammers and fraudsters.  For this John and his team received Certificates of Appreciation from the Criminal investigation Department (CID).  The Bank also received in 2 consecutive years in 2017 and 2018 commendation from CID.  For his leadership and efforts to further protect OCBC customers and the public at large, John will receive a Public Spiritedness Award from the Singapore Police Force in 2019.

John actively contributes to the financial industry in Singapore, sharing his knowledge and helping to build its resiliency.  He has chaired various committees and workgroups on physical security throughout the years.  These committees were organised under MAS, Singapore Police force and the ABS. He was the Chair of the Standing Committee for Physical Security from 2017 to 2019 and developed the guidelines for Physical Security.  He encouraged the conduct of joint security exercises with the Singapore Police Force. Believing in leadership by example, OCBC conducted the first unscripted Ground Deployment exercise involving 200 personnel.  The exercise was a success and many lessons were derived.  John continues to contribute to the industry and now Chairs the Business Resiliency Committee.
