Behind the brands

Geoffrey was a successful businessman from France with a passion for business. After working for several years in Paris, he decided to move to Thailand to pursue his dream of starting his own accounting firm.  Geoffrey noticed that there was a high demand for full-service accounting in Thailand, but many companies were unable to provide this service at an affordable price without sacrificing quality. He saw an opportunity to fill this gap in the market by offering a comprehensive range of accounting services at a reasonable fee.  With this in mind, Geoffrey founded DDES Company, a full-service accounting firm with a genuine commitment to providing personalized service and professional expertise. He assembled a team of expert tax accountants and legal consultants who were experienced in all aspects of servicing, and ensured that his personnel were fluent in Thai, English, Chinese, and French, to cater to the needs of a diverse clientele.  Despite facing challenges in the early stages of the business, Geoffrey persevered and built a reputation for DDES Company as a trusted and reliable financial partner. His dedication to efficient communication and timely responses allowed the firm to build long-lasting relationships with clients who valued their commitment to personalized service and affordable pricing.  Today, DDES Company is recognized as one of the leading accounting firms in Thailand, thanks to Geoffrey's vision, hard work, and commitment to providing exceptional service. He is proud to have made a positive impact on the lives of his clients, and to have helped many small and medium-sized businesses thrive in a competitive market.
