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.

IT Manager

I work in our busy IT department, helping with all things technical. I have often been referred to as a “Button Manager”, if it's got a button, then I manage it! I enjoy working in IT as it allows me to interact with every part of our business all over the world. I am a keen cyclist and enjoy working in our HQ in the English Lake District, a great place for outdoor adventures. I have worked for impact for over 15 years and am very proud of all that we achieve.

I currently regularly travel across Asia consulting for clients and looking after our great people. I'm described as an Energiser Bunny, I bring energy into everything I do, even if I'm stepping off a 12-hour flight! I recover by spending time with my family and exploring the wilderness in NZ with a fishing rod.

There is nothing better than working in a place where we genuinely care for each other, feel supported, and deliver meaningful work that makes a real difference for organisations. Outside of work, I love spending time with my family in nature, exploring new places. I recharge my energy at the beach, enjoy cooking new recipes, and love listening/dancing music with my kids.

I joined in 1982 when the company was two years and totalled four people. I have had the great privilege of what seems like two parallel careers - helping to build and develop our business and working with clients to help them do the same with theirs. I love the variety of my role, that at Impact personal talent is more important than hierarchy, and that we have never waivered from our vision to make a positive difference in the world, through leadership development.
