Joining Impact was one of the best decisions I have ever made. I am responsible for digital enablement and transformation across our global business, data protection programmes, amongst others. I really love the culture at Impact as it is very people-centric, focus driven and a dynamic workspace. Outside work, you will find me playing badminton, swimming, taking long drives and hanging out with friends.

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.

I’ve been working at Impact for over 30 years and now advise on Safety. It’s a demanding job, but Impact also allows me time to have my own adventures.
