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.

Senior Consultant

I bring passion and experience to serve clients in some of the world's most progressive organisations - enabling leaders to perform at their best. I'm told I have an engaging and inquisitive style that connects easily and am particularly effective at getting people to see the wider context. I enjoy adventure and love nothing more than exploring the wilderness with family and friends or tackling an unusual sporting challenge.

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.

Consultant

My role is to build strong, trusted partnerships with clients and help bring our shared purpose to life: liberating human potential and creating organisations that are truly worth working for. I’ve worked across a wide range of roles at Impact, giving me broad experience and a unique perspective on the business. Outside of work, you’ll usually find me out in nature, reading, cooking, or—more likely—chasing after my energetic toddler.

Ava andGayowski
Business development & marketing coordinator

I came to Impact as an Intern in 2023 and here I am again in 2025! That’s because Impact is a great place to learn and the people are even better. Impact’s mission to help people learn and grow is something that resonates with me deeply. My educational background is in mass communications with specialties in PR and advertising. I’m the liaison between our marketing and business development team and my job is to enhance our digital marketing and BD function. In my free time you can find me surfing out on the waves (usually wiping out), horseback riding, or behind a guitar and a microphone.

Global Lead

After 10 years leading the UK, I am now in a global role focused on two areas: one leading a people project, the other focused on marketing. I grew up through Impact as a marketer and love the buzz of building business through brand and storytelling. My other passion is the people and culture here, so this is the ideal combination for me. When I’m not working, I love spending time with my family, enjoying the outdoors and practicing yoga.
