Phisud is one of the founding members of Siam Premier and is recognized in the Thai legal world as being an expert in the field of banking and finance and investment and litigation. He is particularly skilled in advising on legal matters in a governmental, regulatory and institutional context. Phisud has been working in the fields of banking, finance and investment law as well as litigation and arbitration in Bangkok since 1983. Over the last 20 years Thailand has experienced rapid industrial and economic growth, with a commensurate increase in the complexity of the legal transactions undertaken within the Kingdom. Throughout his career, Phisud has been involved in transactions which have contributed to the impressive growth of the Thai private sector and the development of Thai government institutions. As one of Bangkok’s most respected attorneys, Phisud's counsel is sought by a wide range of international and local investors, particularly on matters involving sensitive negotiations with the Thai government. He has substantial experience in advising clients on governmental regulatory and administrative requirements and in assisting private enterprises in their dealings with government entities. His intimate knowledge of the Thai governmental decision making process and his respected network of contacts within the Thai government bureaucracy are instrumental in Phisud being sought out by clients bidding for state projects as well as government licensing. In particular, Phisud has been the advisor to numerous private enterprises in relation to their applications for government licencing in the areas of life insurance, mutual fund management, on-line lotteries, telecommunications, and banking. While assisting in sensitive negotiations, he has advised clients on their strategic options in their dealings with the relevant government entities in respect of these bids and applications and, on approval of his client’s projects, has overseen the subsequent establishment of their operations in Thailand.
