Erin andTetarenko
Senior Consultant

My enthusiasm for life is ignited when surrounded by inspiring people and growing through exploration. Born in Canada, my passions have led me to travel within various countries. I joined Impact motivated by their commitment to empowering people and business cultures to thrive while making a positive difference. As a coach and facilitator, I draw on over 10 years facilitating in personal development and wellness.

Hillary andO'Dell
Project Manager

I am a program manager, and I love that every day is different, from working on different tasks involved to make a program run smoothly to talking and meeting clients. I come from a hospitality background, so I love the client-facing aspect of my role here at Impact, as well as making sure every piece of the program is on schedule. Outside of work, I am always doing something like teaching dance, travelling, and going to the beach!

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!

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.

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!

Program Manager

Every day is a new adventure at Impact. As a Program Manager, I enjoy meeting people from all walks of life in the professional sphere. With my background in marketing, sales, customer service and business administration, Impact has provided an opportunity for me to utilise my communication and organisational skills on meaningful programs. In my spare time, you’ll find me practicing yoga, surfing, travelling, and spending time with friends and family.

Alassane andDiop
Consultant and Facilitator

I’m a consultant with an international and multicultural background and approach my work with contagious enthusiasm and commitment. My experience working with both large corporations and small startups gave me a deep insight into overcoming business operational hurdles and developing proactive trainings paths to grow and enhance teams. Over the years I’ve gained experience in facilitating and promoting dialogue in B2B partnerships and creating organizational innovation projects.

Karen Jaques Impact International
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.

Jo andAppleby
Head of Partnerships

I design projects to bring Sustainable Development Goals to life and get them into every programme we deliver. Globally. Universal in nature and relevant for all, the SDGs tackle the biggest issues facing our planet and everyone on it. I sit on the consultant team, support our Community Action Learning function and the wider and I’m the Impact UK representative for UNGC. I love running in the fells.

Annie andTan
Regional Account Director

As an avid explorer of adventure and lover of cultures, I’m glad to have found my home base with Impact. My role is all about sparkling curiosity, connecting values, and empowering lives through meaningful work, passion, and fun! Coffee and Tea are my best friends, and I love taking road trips on bikes and capturing candid moments of people and food! You can always find me in the biography section of any bookstore!

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.

 

Senior Director - Client Services, Americas

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.
