Mayer Brown JSM has appointed tax partner Pieter de Ridder its new managing partner in Singapore as his predecessor, Kevin Owen, retires.

De Ridder takes over the 16-lawyer office from Owen, who relocated from Hong Kong in 2011 to launch the outpost. Owen had been a partner with legacy Johnson Stokes & Master and stayed through the Hong Kong firm’s merger with Mayer Brown in 2008.

Singapore is the only new Asian office established following the decade-old creation of Mayer Brown JSM. Elsewhere in Southeast Asia, the firm inherited legacy JSM’s Bangkok, Hanoi and Ho Chi Minh City offices. In December, Chicago-based Mayer Brown announced it would launch a Tokyo office in the first half of 2018.

De Ridder handles tax matters for mergers and acquisitions and financing transactions with expertise in Indonesia-related deals. He joined Mayer Brown JSM in 2015 from Dutch firm Loyens & Loeff, where he had been a partner for 20 years and was then head of the Singapore office.

The U.S. firm has made several hires in Asia recently. For the Tokyo office launch, Mayer Brown poached former Ashurst Tokyo head Rupert Burrows; earlier this month, it also hired former Debevoise & Plimpton counsel Brian McKenna as a corporate partner in Hong Kong.
