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.

Exploring Human and Organizational Creativity 
I have 8 years of experience in the food and beverage industry, focusing on talent and organizational development. Discovering coaching inspired me to apply it in the field, seeing people transform through intrinsic motivation. This led me to join a coaching firm, supporting various industries.  Motivated by the question, "How can individuals and organizations unlock their potential?", I joined Impact to further develop my expertise.  I enjoy playing the drums and held a live performance last year. My motto: "Immerse myself in what I am passionate about while working."

Hi! I am an occupational psychologist, coach and trainer! I have been working for over 20 years to help companies develop and enhance their greatest capital, their people! I met Impact many and many years ago, and I am still proudly part of it! In my spare time I am a theatre actress, a traveller, but above all... a mum!

Lou andMcDonald
Head of Brand

Sum myself up in a paragraph? There’s a challenge! And maybe a good starting point. I like challenge. I like the challenge of grabbing attention with interesting, useful and relevant marketing. From a new website or re-brand to a sell-out festival, for me it’s all about customer first. I like a physical challenge too, and the challenge of how long I can last without listening to music!

Daniele andFilzi
Experiential Solutions Specialist

With over 20 years at Impact, I've contributed to the design and delivery of over a thousand programmes. And what if the secret of success is to continue to refine something even if you've done it dozens of times? Outside of work, I like gardening and interior design. I live on the crest of an extinct volcano, with the Mediterranean Sea to my west. After sunset I keep fit by jogging around a golf course.

Doug andGreenhough
Head of Learning Tech

I love both learning and technology, so leading Impact’s learning tech R&D is a fantastic gig. Technology can sometimes feel in conflict with the humanity we seek to serve, but thoughtful application of tech immerses us in challenging experiences, brings us closer together and helps us to learn the most important, most human skills. My approach to learning tech (and life, for that matter) echoes Impact’s practice: experiential and human-centred.
