Wendy Lee, Impact

Wendy andLee andBerger
Global Lead, Operations

I was lucky enough to join as the third member of the US team in 2006 and have done almost every role in the business including design, delivery, sales support, project management and even bookkeeping! That breadth of experience has helped me in my current leadership role, it allows me to understand the business from multiple perspectives and focus on operational excellence. My nickname is Wiki because I can usually help find the answer!

Nao andMatsushita(Noa)
Coordinator

'Helping People Shine on Their Own Stage' As a restaurant manager, I wanted to create more than just a place to eat. By drawing out each team member’s strengths and aspirations, I saw the power of a team that values individuality. This led me to study coaching. I later realized that growth also depends on the organization, so I now study organizational development. My goal is to help people and organizations grow together, enabling everyone to shine as themselves and fulfill their potential.

Support

In support we deliver on programs and manage day-to-day operations and infrastructure. I really enjoy my role as it’s very diverse, one day I am canoeing on Windermere and the next cleaning boots! My favourite programs feature outdoor activities and journeys. People see me as a steady pair of hands and a person who does a quality, professional job. Outside work I keep myself fit and active, and enjoy chilling out with my wife Emma and travelling in our camper van.

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.

Simon andWheatley
Senior Consultant

Analogue at birth, digital by requirement. I don’t do Facebook, and have nothing to do with hashtags. Is this bio going online? Eurgh! I am an eye-to-eye, face-to-face human being. I elevate small talk to medium talk. Then, (on a good day) to infinity and beyond. That’s my job. Favourite pastimes: Good days. Woodland crafts, festivals, and campfires. Specialist skills: Reading body language; parallel parking.

Consultant and Facilitator

I joined Impact Italia in 2021 and the magic started happening! Energy, active listening, and continuous exchange are the key elements that characterize my personal and professional life. My purpose here is to design and facilitate ‘ad hoc’ learning solutions that can release transformation and changement regarding the different spectrum of needs that can have organizations. In my spare time I practice dance and yoga, I am travel-addicted and I love to cook to share the results with my loved ones.

Mario andGianAndrea
President and Founder

I’ve been many in my working life: an HR Director, an entrepreneur, a leader, a coach, a salesman, a visionary, a confidant, a manager. And a friend. And I am still excited (and sometimes anxious) when I meet a new group of people. I genuinely enjoy it! This is the reason I'll probably work for another decade! The only difference compared to the past: today I can afford to only work on projects and with people that I really like and that gives me the feeling that it will be great fun!

Simon andWagstaff
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.
