Business Support

I always enjoyed working for companies who share my values and whose work I can be passionate about. I love that Impact wants to make a difference and has the purpose to help build companies worth working for. I enjoy a good adventure and have a passion for travelling, my latest adventure being swapping London life for the great outdoors of the lovely Lake District!

Clive Barrow
Consultant

I’ve had a passion for enriching lives through deeply practical experiential learning, and immersion in adventure around the world for most of my career. As a British Army officer, expedition leader, leadership consultant and executive coach I’ve had the enormous privilege to facilitate learning experiences for others in over 40 different countries. My greatest gift - apart from my wife and kids - doing the work I love!

I am responsible for “Re-Born Strategy” in Impact Japan, I am passionate about developing people and our organisation by executing all Re-Born strategic agendas. As a facilitator, I love creating and sharing the precious moments together with executives and managers who are reflectively asking themselves what leadership they would like to realise in their life/work. What I love most is drinking after working hard to make effort in realising my vision.

Giving my all to grow and enjoy work
I have back-office experience in the apparel, IT, equipment manufacturing, and consulting industries. Most recently, I worked in HR for a cosmetics brand, handling recruitment. Believing in developing existing talent over competing for new hires, I joined Impact to unlock my own potential while working towards the company’s mission.

I'm passionate about organizational psychology and behavior and joined Impact after years of experiences in global business. I was inspired by the way Impact uses unique adventurous, experiential learning solutions, and now am passionate to help clients achieve real improvements in performance as a consultant. When I am not at work, you can find me walking around the city with my camera.

Lou McDonald
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!

'Continuing to "enjoy" life'
My lifelong mission is to continue positively influencing both myself and those around me, while persistently seeking enjoyment.
Throughout my career, I've had various experiences, from utilizing cutting-edge technology in logistics to engaging in gritty tasks. Through these experiences, I've realized the importance of finding meaning and joy in everything I do. Although sustaining this mindset is not easy, I am committed to continuous learning to become a professional to bring a positive impact to people and organisations.

I love the variety of my role, working with global clients on complex projects and learning from inspiring Impact people, no two days are the same. I’m responsible for the quality of customer service, building excellent client relationships, providing commercial strategies with meticulous project scoping and planning, alongside first class solution delivery and evaluation. I love the outdoors; walking, running or camping with our two boys and crazy cocker spaniel.

Safety Quality Controller, Master Coordinator

Before Joining Impact in 2002 I worked as an outdoor guide for nature tourism, kayaking and trekking in the ocean and forest. Using this experience, my strengths are in creating and coordinating programmes that provide learning experiences through outdoor activities. Beyond this role I wear several different hats, such as managing our website and managing H&S. Personally, I love to do challenging journeys by sea kayak and bike in many countries.

Samantha Rostas
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 consult with our customers to understand their business aspirations and challenges before recommending a learning solution that is going to exceed their needs. I maintain close relationships to ensure they receive the best possible service. I work across all market sectors and levels; however, I'm particularly passionate about graduate development. Out of work, you’ll find me up a mountain attached to either a rope or a pair of skis.

As a Program Manager at Impact, I get to utilize the communication and organizational skills gained from my 6 years of customer service experience and owning my own business.

Martin Smith
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.

Pete Hallworth
Senior Consultant and Facilitator

I have been active with Impact for several years after an international career in sales and marketing. One of my main passions is to foster better leadership. Leaders that inspire, that provide their team with development opportunities, and that have vision and courage will change the world; for the better.  Another passion is helping start-up entrepreneurs get off the ground. Kindness and curiosity are two words I aspire to live by.  It is also very important to me to be kind to our planet.  It’s the only one we have.

Doug Greenhough
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.

A lifelong passion for learning and leadership brought me to Impact, and I couldn't be happier with my decision. As a designer, facilitator, and thought partner, I embrace a scholar-practitioner mindset, running to the issues and engaging others with clarity, empathy, and authenticity. My favorite activity of each day is laughing, playing, and making up bedtime stories with my kids. They're hilarious!
