Dean Mounsey Impact

Dean andMounsey
Country Manager

I'm surrounded by gifted people who do anything for each other - I mean anything. I find this very humbling. Two decades at Impact have taught me the value of compassion, loyalty, striving for excellence in everything you do and always getting back up when you fall down. This has helped me gently hold that most elusive of holy grails, true meaning at work. I love and am gratefully centred by my wonderful family. I seek adventure wherever I can and love being high up in mountains.

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.

I am responsible for our support team and coordinating the Warsaw office. I project manage, which includes monitoring facilitation, communicating with partners, background logistics and managing course equipment for our fantastic experiential projects. Since joining in 2005 my role has developed through office manager and H&S advisor. I love what I do and the people I work with. Personally, I am getting to know my young son and understand his world. Life is a journey.

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.

Accountant

AKA Bloodaxe. I am an accountant at Impact. When I am not at work, I enjoy spending time with my family, cycling and heavy metal. Not all at the same time, though – that’d be dangerous.

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!

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.

As a consultant, organisational psychologist, account manager and researcher…I endeavour to encompass all the different aspects of life in the organisation! To me the organization is a magic happening between individuals, groups and their work contexts.

Lucky me, I have a job that allows me to be a Human Doing and a Human Being. I love connecting and building relationships with people through my work.

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.

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!
