Support

I support delivery of high quality, safe and challenging programmes and keep the operations infrastructure in a safe and workable condition. I have been lucky to have worked in some amazing places around the world with some amazing colleagues and participants. Working from Base still takes some beating though! When not working I enjoy having adventures with my family, exploring the Lakes and keeping fit by running, climbing and riding my Cyclocross bike.

Support

In support we deliver on programs and manage day-to-day operations and infrastructure. I really enjoy my role as it’s very diverse, one day I am canoeing on Windermere and the next cleaning boots! My favourite programs feature outdoor activities and journeys. People see me as a steady pair of hands and a person who does a quality, professional job. Outside work I keep myself fit and active, and enjoy chilling out with my wife Emma and travelling in our camper van.

Senior Consultant

I’m passionate about learning and helping people get the best out of themselves. I spent over 10 years in Learning & Development with a Fortune 15 company helping develop and deliver programs to Executives, Middle Management, and Aspiring Leaders from all different parts of the business. I believe that understanding and leveraging diversity is one of the biggest strengths of any organization and I really enjoy helping groups work towards that reality. When I’m not working, I enjoy spending time with my wife and 2 daughters as well as rooting for any and all Philly sports teams. I also have a pretty sweet record collection.

Senior Consultant and Executive coach

I see life as a gift and a journey. I bring in my backpack some of the experiences I had the luck to have: nuclear engineering and 25 years as a manager in various industries in various parts of the globe. And then Impact. I feel excited when I see the very essence of situations emerge: in individuals, groups, communities, and organisations. I am fond of endurance sports and am a passionate soul explorer.

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!

Doug Greenhough, Zinco

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.

Program, Manager

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. My favorite aspect of the role, is seeing a program be designed and developed over time, come together in the end. In my free time, you will find me cooking, hiking, painting, or playing with my dogs!

Shino andTakahashi(Shelly)
Assistant Manager, Human Development

'Making Work Enjoyable for Children' I’ve spent 17 years in retail, gaining experience in sales, customer service, training, HR, and recruitment. This taught me that business growth relies on people’s growth, inspiring me to pursue my own and motivate children. A key moment was a training program at Impact Co. 11 years ago, sparking my passion for talent and organizational development. As a working mom, I focus on balance—committing to work weekdays and spending time with my toddler daughter on weekends. This balance is key. 

Sally Fleming, Impact International

Sally andFleming
Senior Consultant, UK

My focus is on developing responsible leadership. I bring a warm combination of broad industry experience, academic rigour, Yorkshire humour and humility. My motivation and purpose is to help us mutually learn and create a more sustainable, compassionate and just world.  Fortunately, my spirited playful side, wilderness adventures and inclination toward anything shallow on a Friday night ensures people still invite me to parties despite all of that.

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?

Business strategy excites me and implementation more so! My role is to head up our digital strategy and take Impact’s experiential face to face practice in to the digital world, strengthening our blended programme work and building digital solutions that serve our clients’ needs in these times of exponential change. I’m a daughter, sister, aunty, wife and mum. I adore sport and adventure, especially cycling, snowboarding, swimming and surfing.

Assistant Manager, Planner

Working as a planner at Creative and Marketing Department since 2019. Before Impact, my career was mainly on the position of sales and marketing at the bank and advertising agency. My focus is on the capacity building for both individual and team. Virtual team building is one of the fatal themes because I am working as a full remote member. I love traveling around the world with my backpack and enjoying beautiful local delicacies!

Mario andGianAndrea
President and Founder

I’ve been many in my working life: an HR Director, an entrepreneur, a leader, a coach, a salesman, a visionary, a confidant, a manager. And a friend. And I am still excited (and sometimes anxious) when I meet a new group of people. I genuinely enjoy it! This is the reason I'll probably work for another decade! The only difference compared to the past: today I can afford to only work on projects and with people that I really like and that gives me the feeling that it will be great fun!

Manager, Business Consulting Department

Being a manager of the delivery team in Impact Japan, I have been putting great effort and energy into realising our “Re-Born Strategy” from the delivery quality aspect. For my leadership style, creating trust is the most important factor. I support my team by creating trusting relationships, and as a facilitator, I use this quality to create a completely safe and open learning space in programmes. I love having a good time with people, drinking and karaoke.

I'm based in Thailand, a country of beautiful islands, good food and nice people. I have a lot of fun working with people around the world. I have more than two decades of international finance and accounting experience. My real challenge is working with Inland Revenue offices in different countries! I love to explore the world through reading and travel and one day wish to have a little cafe where people can sit and have a coffee or few drinks and craft together.
