Account Director

As an Account Director with Impact, I’m able to leverage my ten years of Business Development and Account Management experience.  I thrive in environments where I am able to develop and uncover new opportunities with partners and businesses. Most of all, I am a people person and love building trusting relationships. In my spare time, you will find me spending time with my husband, two boys and our dog.

Head of Creative Change

I’m passionate about experiential learning and learning through play. I enjoy inspiring groups to better themselves, to collaborate and share skills, to be ambitious for each other and those around them. I have extensive experience working in the cultural, education and corporate sectors. I’m an award winning theatre maker who has directed shows for the Queen, the Prime Minister and West End audiences. Out of work you’ll find me building Lego unicorns with my daughter.

Yuki andOkamoto(Yuki)
Master Coordinator

Since 2006 I have coordinated programme delivery. This involves meeting facilitators and consultants to design great modules, using creativity to ensure participants have profound learning experiences that add value to their organisation. I manage project set up and use technical skills such as abseil belaying. I have a teaching licence to teach PE. Now I enjoy working using my body, so I love to do exercise and jogging, swimming, gymnastics, and most outdoor things!

Sam Rostas, Impact International

Samantha andRostas
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.

Connor andGildert
Sales Operations Administrator

I work alongside our business development team to ensure we provide quality service to our global clients. I also work closely with our internal teams to help do our bit to help develop the local community. Impact gives me the space to be myself, which usually gets me into trouble...

Zuzanna Naruszweicz, Impact
Poland
Zuzanna andNaruszewicz
Head of Consultants & Project Management

My area of focus is “Sustainability and Responsibility”, and I am passionate about using my years-long experience from the non-profit sector in my present job. In addition to that, I support the team in any other possible way – in translations, formatting documents, gathering data, and communication with associates. I love biking, backpacking and vegan cooking.

Marjolein Smith

Marjolein andSmith
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.

UK
Dr andKaren andJaques
Associate

I love exploring issues that my clients face and helping to find practical solutions. My other roles include developing Impact’s thinking around leadership and team development, and using systemic perspectives to encourage responsible leadership in business and society. Convincing, articulate and credible as a facilitator, I'm passionate about helping people realise their full potential...including myself! I love ski-mountaineering and any ways to access wild places.

Andrew Robinson, Impact International
UK
Andrew andRobinson
IT Manager

I work in our busy IT department, helping with all things technical. I have often been referred to as a “Button Manager”, if it's got a button, then I manage it! I enjoy working in IT as it allows me to interact with every part of our business all over the world. I am a keen cyclist and enjoy working in our HQ in the English Lake District, a great place for outdoor adventures. I have worked for impact for over 15 years and am very proud of all that we achieve.

Doug Greenhough, Zinco
UK
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.

Mario GianAndrea, Impact Italy

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!

Sam Parkin

Samantha andParkin
Credit Controller

I'm part of the UK Accounts Department and I'm responsible for issuing all of Impact's sales invoices both electronically or by post in a multitude of currencies sent to our clients all over the world. I work closely with lots of my colleagues both here in the UK and overseas. Out of work I enjoy spending my time cycling in the beautiful Lake District Countryside, walking and spending time with family and friends.

Asia Pacific Finance Director

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.

Haruka andMaruyama(Maruko)
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!

Dileepan andDhanasekaran
Digital Business Support Analyst

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.

Delfino andCorti
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.

Simon andWheatley
Senior Consultant

Analogue at birth, digital by requirement. I don’t do Facebook, and have nothing to do with hashtags. Is this bio going online? Eurgh! I am an eye-to-eye, face-to-face human being. I elevate small talk to medium talk. Then, (on a good day) to infinity and beyond. That’s my job. Favourite pastimes: Good days. Woodland crafts, festivals, and campfires. Specialist skills: Reading body language; parallel parking.

As a Digital Marketing Executive I am responsible for a broad range of global marketing projects and activities. I believe in Impact's mission, values, methodology and expertise, and I hope that thanks to my work more people around the world will hear about the great changes we make for organisations and their people. I am a nomadic soul and travel often to discover, experience and learn how the world and people differ.

As a mom to 4 girls I am constantly reminded that I am human, it's inescapable.

Giuseppe andFlorimonte
VP and senior consultant

Father of three, happily married to one, and manager of some, I love numbers and sales, but I also like to ideate, design and deliver challenging programmes, either in training or consultancy. In Impact for more than 15 years, I still very much enjoy the consultancy process, especially account and client management. At work, I am acknowledged (and sometimes blamed) for dreaming big and joking a lot!

Arianna Bianchi

Arianna andBianchi
Consultant and Facilitator

As a consultant, I hope to be a catalyst for change, helping others to discover what their real needs are. Empathy, curiosity, creativity, organisation and strong sense of duty are the things that most characterise me. I love the adventure and the discovery of travelling, organising outdoor trips with friends in close contact with nature… But also sharing a gin lemon or a barbecue at home is not so bad!
