Tilleke & Gibbins has expanded its Bangkok office after hiring Joseph Tomkiewicz and Supasit Boonsanong as co-heads of its energy practice, and Prisna Sungwanna as a corporate partner.
While Tomkiewicz joins from Chevron South Asia, where he was a general counsel, Supasit and Prisna were previously senior partners at Chandler MHM. They will be joined by two counsel and four associates.
Tomkiewicz has more than 28 years of experience. In Chevron, oversaw all legal affairs for upstream operations across jurisdictions, including Bangladesh, Cambodia, China, Japan, Myanmar, Thailand, and Vietnam.
Meanwhile, Supasit has over 35 years of experience as an oil and gas industry lawyer in Thailand. He specializes in banking and finance and mergers and acquisitions, and advises energy and natural resources companies.
Prisna represents companies in Thailand and beyond on merger and acquisition matters, including joint ventures. She also advises on establishment of legal entities in Thailand and obtaining foreign business licenses and certificates.
Last year, Tilleke & Gibbins hired Jay Cohen as the director of its Cambodia practice. With these appointments, the firm currently has 30 partners and over 150 associates across Southeast Asia.
