Managing Partner


Tiziana Sucharitkul is managing partner of Tilleke & Gibbins and oversees all aspects of the firm’s work, including directing the growth of the firm’s business, monitoring firm performance, and ensuring delivery of extraordinary client service. In addition to her steady leadership of the firm’s internal activities, a key aspect of her role is a focus on Tilleke & Gibbins’ international strategy and the firm’s relationships with global law firms and clients. With her clear vision and dedication to nurturing Tilleke & Gibbins’ status as a trusted partner for businesses operating in Southeast Asia, Tiziana works to increase the firm’s international profile and its ability to serve clients from around the world.

A recognized leader in the global legal community, Tiziana serves as chair emeritus of the Board of Directors of Lex Mundi, a leading legal network of which Tilleke & Gibbins is a member—and for which she previously served as chair and as a member of the executive committee. A member of the Law Firm Management Committee of the International Bar Association since 2021, in 2024 she was appointed as a co-vice chair of the committee. In addition, she is a sought-after contributor to webinars, panels, and articles for her insights on topics such as law firm management, diversity and inclusion in the legal profession, and international cooperation in the legal industry.

Tiziana is also an accomplished litigator, and she spent many years as director of the firm’s dispute resolution and litigation group, where she earned repeated accolades as one of Thailand’s leading dispute resolution lawyers by publications including The Legal 500 Asia Pacific, Asialaw Profiles, and Benchmark Litigation, which listed her in 2020 as one of the top 100 female litigators in the Asia-Pacific region for her work in commercial and transactional disputes and government and regulatory matters. She has frequently represented international clients in diverse industries including technology, financial services, consumer goods, luxury goods, and transportation.

Tiziana is admitted to the State Bar of California, the US Court of Appeals for the Ninth Circuit, and the Northern District of California Court.

Besides her legal work, Tiziana is also a supporter of the local community through involvement in legal and social efforts in Bangkok and beyond. She serves on the board of Bangkok Patana School, where she sits as the head of the Human Resource Committee, the chair of the Steering Committee, and the secretary of the Foundation Board.

Through her commitment to serving clients by building Tilleke & Gibbins’ profile and capabilities, Tiziana’s leadership is integral to the firm’s ability to provide full-service legal guidance for international, regional, and local businesses active in Southeast Asia.
