A&O Shearman appoints Sarah Wilson as Bangkok office managing partner

Sarah succeeds Suparerk Auychai, who is retiring from the partnership and will continue to work with the firm as a consultant. Suparerk also serves as head of the office corporate practice, and he will be succeeded in that role by Noparat Kaewsringarm.

Sarah joined legacy Allen & Overy in 2007 and has been a partner since 2019. She specializes in project finance transactions in the power and infrastructure sectors across ASEAN and the wider Asia Pacific region, as well as broader financing transactions in Thailand. In her new role, Sarah will focus on leading A&O Shearman’s operations in Thailand and continuing to deliver high-quality service to its clients.

Gautam Narasimhan and Daniel Ginting, co-managing partners of ASEAN, said: “Sarah has a deep understanding of our clients’ needs in Thailand and the ASEAN region, making her ideally suited for this role. She has built strong relationships with major clients, contributing to A&O Shearman’s reputation both in Thailand and across the ASEAN region. We are confident that under her leadership, the Bangkok office will continue to thrive. We would like to thank Suparerk for the contribution he has made to the firm and congratulate Sarah on her appointment.”

With a first-class team of international and Thai lawyers, A&O Shearman is one of very few global law firms in Thailand providing a ‘one-stop service’ for domestic and cross-border offerings and is well known for its deep knowledge and understanding of the Thai business and regulatory environment. A&O Shearman achieved Band 1 rankings in the Chambers 2025 Asia Pacific Guide for Thailand across banking and finance, projects and energy, corporate/M&A, capital markets and aviation.
