Consultant

I’m a Consultant and Client Lead at Impact, and as a mum I’m reminded daily of what matters most: learning, growing and giving things my best. That’s the approach I bring to my work. Over the past eight years, I’ve had the privilege of working with an incredible team while meeting and getting to know wonderful clients. I support experiences that help people grow, connect and feel seen. I believe in the power of small moments and the ripple effect they create, and I hope the work we do today helps shape a kinder, more purposeful future, especially for the next generation our children will inherit.

I joined Impact back in 2017, and already in my first year I fell in love with the culture and the people. 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.

Sue andHunt
Board Member

My first school had the motto 'Aim High' and that has always resonated with me. I rise to a challenge, both personally & professionally, enjoying new situations and solving difficult & complex problems. I certainly had plenty of those as International Treasurer of Goldman Sachs and as a Director for the London 2012 Olympics & Paralympics. I joined the Board of Impact to help grow the business globally. It's great to be part of such a diverse global team!

Senior Consultant

Having a limited number of words to describe myself I choose...that is one of the keywords, among decide, like, wonder. There are many others. Working with people, I value being aware – of a person, a group, and also of words being used. I think of them as a code passing through our minds – all that is within the light of consciousness shapes our experiences and reactions towards the world. So, what do you choose?

I have been supporting people in communication for 20 years. Initially as a consultant and currently as a trainer, coach, and mediator. I am passionate about people and the complexity of human nature, and like to help tame this complexity for a specific purpose. Socially involved, I'm also a mother of three. Between all this, I find balance in meditation, yoga and nature.

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.
