Executive Summary

With 21 years of experience and a Thai SEC registered auditor, Teerasak has an encyclopaedic knowledge of accounting issues in a wide variety of industries, both in and around Thailand. He has performed extensive control assessments, developed management recommendations for clients, led initial public offerings, and conducted audits for subsidiaries of US listed companies.

Teerasak joined BDO in Thailand because he believes in the firm’s commitment to providing customised, client-centred advisory services. “This is the perfect opportunity for me,” he says. “By helping to lead a young firm like BDO in Thailand, I can ensure that the right methods are implemented from the start. For example, we use technology to minimise manual processes and provide a better service. The increased efficiency lets our team focus on solving the more complex issues that face each individual client.”

Such efforts require a deep understanding of what each client is trying to do. “My role as a consultant is much more valuable if I know the client well enough to become their partner and adviser,” he says. “By working with them to find the best way forward, I also gain much more knowledge and experience.”

As for leading his team of auditors at BDO, Teerasak’s enthusiasm is unmistakable: “I coach them every day, sharing lessons I’ve learned about accounting, business, and the people we try to help. We are a team of analysts and problem-solvers, and I'm thrilled to be part of an organisation that puts a high value on helping our clients succeed.”
