    Until his first “retirement” on 30 June 2014, David was a partner in PwC Singapore’s Tax practice where he spent most of his time dealing with international advisory work across a whole spectrum of industries, including energy, communications, construction, shipping, real estate, hospitality, banking and insurance.

    As a partner in the Firm's Financial Services tax practice, he had initiated, headed and grown the Fund Management division into the largest contributor to the FS tax practice overall. In this role, he was regularly involved in helping clients structure their venture capital, private equity and real estate fund projects, and worked closely with the firm’s Mergers and Acquisitions, and Banking and Capital Markets teams in this regard. He has, as a result, extensive experience in corporate reconstructions and group reorganisations for funds and multi-national groups.

    Apart from his client-facing role, David also led the Tax training and technical department for the Firm as well as its tax public relations.

    From 2015 to 2019 he set up and ran DSC, leveraging off his many years of experience, aimed at filling the middle-market pricing and experience gap that exists in the tax environment.

    He came out of retirement to join Grant Thornton Singapore as Head of Tax in July 2019 and became Practice Leader of the firm in July 2020 while maintaining his Tax Leadership role. He ceded his Practice Leadership role to younger blood in April 2024.

    David has now had some 43 years of tax experience, 35 of which have been in the Singapore and South-East Asian tax and business environment.

    He has now “retired” for the second time but has taken up the reins again of DSC, with a view to servicing a select band of clients who want the insight of years of tax and business experience, rather than the hurried cut-and-paste or AI slop that is in danger of becoming more prevalent.

    On the external front, David was for many years a member of ICPAS’ Taxation and Levies Committee and latterly performed the same role for the Singapore Institute of Accredited Tax Professionals. He wrote the Singapore volume of CCH’s Tax Planning and Compliance in Asia and authored the chapters on Hedge Funds and Private Equity Firms, and on Group relief in The Law and Practice of Singapore Income Tax. He has appeared on numerous occasions on TV and radio, written frequent articles for newspapers and technical journals, and made countless public presentations.

    A graduate of Cambridge University, David spent his formative years with Price Waterhouse in London, initially in audit before making a move to the tax department in 1983. He then spent two years with Price Waterhouse in Melbourne, Australia before migrating to Singapore in 1991. He is a member of the Institute of Chartered Accountants in England and Wales as well as the Institute of Certified Public Accountants of Singapore and is an Accredited Tax Advisor with Singapore Chartered Tax Professionals.
