John andMatthews
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.

Graphic Designer

Born in the Netherlands, I aim for simplicity, clarity and efficiency in my designs and processes. I appreciate Dutch, German and Swiss designs for their geometric boldness and witty solutions as well as the minimalism and sense of calm in modern Japanese design. To soothe my creative brain, I put on my running shoes and head for the beautiful hills that surround me to rediscover my peace and tranquillity.

Martin andSmith
Senior Director - Client Services

I lead the overall relationship with our clients, working closely with them and our brilliant Impact team to build powerful solutions to their most pressing challenges. I’m a bit of an oddity - an Aerospace Engineer by training and experience who, for the last 20 years, has found my passion in helping others thrive at work.  I‘m based in Chicago with my wife, and when not running on the lakefront, I’m probably wrestling with an ornery cat.

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. Outside of work, I love spending time with my family in nature, exploring new places. I recharge my energy at the beach, enjoy cooking new recipes, and love listening/dancing music with my kids.
