Warangkana (Lek) Posinsomwong
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.

Over the past 16 years at Impact I've worked around the world with some truly wonderful people.

I love the outdoors, and spend many hours at the beach with my wife and daughter.

Daniel Osborn
Business Data Analyst, UK

Having the job title 'analyst' means that I've been lucky enough to get involved in a wide range of projects both internally and working with clients. I love helping people get the most out of the tools they are using, making processes as efficient as possible and understanding data – all of which is part of my work every day. Outside of work, you’ll usually find me in the Lake District somewhere with my family.

Senior Consultant and Executive coach, Italy

I see life as a gift and a journey. I bring in my backpack some of the experiences I had the luck to have: nuclear engineering and 25 years as a manager in various industries in various parts of the globe. And then Impact. I feel excited when I see the very essence of situations emerge: in individuals, groups, communities, and organisations. I am fond of endurance sports and am a passionate soul explorer.

Lou McDonald
Head of Brand

Sum myself up in a paragraph? There’s a challenge! And maybe a good starting point. I like challenge. I like the challenge of grabbing attention with interesting, useful and relevant marketing. From a new website or re-brand to a sell-out festival, for me it’s all about customer first. I like a physical challenge too, and the challenge of how long I can last without listening to music!

With over 20 years at Impact, I've contributed to the design and delivery of over a thousand programmes. And what if the secret of success is to continue to refine something even if you've done it dozens of times? Outside of work, I like gardening and interior design. I live on the crest of an extinct volcano, with the Mediterranean Sea to my west. After sunset I keep fit by jogging around a golf course.
