A global leadership facilitator/coach, I partner with you to meet challenges in uncertain, complex environments. I focus on what works in order to create programmes where learning is used right away. I am a bad surfer/golfer, lapsed runner and improving tennis player.

Verity andBellouere
Project Manager

I look after clients from tender, right through to evaluation. Three of my four main clients are global, so it’s about managing time differences too. I am the 'go to' person for many other things as I've worked here since 1991. I'm open, honest and always have an opinion! Questions usually start with “you will know...” I like nothing more that being up a hill in the Lake District or French Alps and camping in Cornwall with family and friends.

Jo andAppleby
Head of Partnerships

I design projects to bring Sustainable Development Goals to life and get them into every programme we deliver. Globally. Universal in nature and relevant for all, the SDGs tackle the biggest issues facing our planet and everyone on it. I sit on the consultant team, support our Community Action Learning function and the wider and I’m the Impact UK representative for UNGC. I love running in the fells.

The Boss!

I co-founded Impact in 1980 to explore adventure and experiential learning in people development. It worked! We now inspire and develop people worldwide. Shared values, a common purpose and a spirit of adventure bind us together. With over 200 colleagues working in the UK, Europe, America and Asia Pacific, we have a solid reputation for enabling clients to build leadership capacity and navigate complex change. To stay grounded, I rear rare breed cattle and sheep.

Japan
Akira andMatsumoto(Mikey)
Assistant Manager, Facilitator

With nearly 18 years in the retail industry, I held roles such as sales, store manager, trainer, and area manager. These experiences taught me that when people grow, organizations grow. Supporting others made me reflect on my own growth and whether I still had something to offer. To challenge myself, I moved into a new industry. Now, I work to create training experiences that resonate emotionally and leave a lasting impression—while continuing to grow with my clients.

Kate andWolf
Sr Director, Client Services

I’ve spent my career partnering with clients to solve problems and drive their organizations forward. As Teddy Roosevelt (and then Leslie Knope) shared: “The greatest gift that life can give is to work hard at work worth doing.” I’m honored and thrilled to do meaningful work with my colleagues at Impact, leveraging powerful experiential learning experiences for our clients to create the ‘leaders they wish they had’. Outside of work I love to explore the beauty of Oregon by foot, bike or boat.

Senior Consultant, UK

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.
