Asia Pacific Finance Director

I'm based in Thailand, a country of beautiful islands, good food and nice people. I have a lot of fun working with people around the world. I have more than two decades of international finance and accounting experience. My real challenge is working with Inland Revenue offices in different countries! I love to explore the world through reading and travel and one day wish to have a little cafe where people can sit and have a coffee or few drinks and craft together.

Bridging future-oriented research, innovation, and design principles and practices, my focus is on optimising our core business through developing and delivering resilient, human-centred solutions.

General Manager, New Zealand
Asia Lead - Solutions & Practice

I love what I do! Each day is so different and brings challenges, interactions, and rewards. In my different roles I get to lead, mentor, coach, create solutions, and deliver life-changing experiences. I’m lucky to be surrounded by amazing colleagues - whom I get to call friends. I relax by spending time in nature – usually with my loving family but with the occasional solo adventure as well!

Graphic Designer

Born in the Netherlands, I aim for simplicity, clarity and efficiency in my designs and processes. I appreciate Dutch, German and Swiss designs for their geometric boldness and witty solutions as well as the minimalism and sense of calm in modern Japanese design. To soothe my creative brain, I put on my running shoes and head for the beautiful hills that surround me to rediscover my peace and tranquillity.
