Project Coordinator

I support the set up and administration related to the end-to-end implementation of client solutions in the UK and worldwide. I am an organised and passionate team player and I enjoy working as part of the various Client Service Teams who manage our clients. Not originally from the Lake District, I feel very lucky to now live and work in such a beautiful place in the UK. I love spending time with my friends and family and keeping fit.

Head of HR

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.

Global Safety Advisor

I’ve been working at Impact for over 30 years and now advise on Safety. It’s a demanding job, but Impact also allows me time to have my own adventures. I am a qualified International mountain guide and run yearly expeditions to East Greenland. These experiences give me a healthy dose of “on the edge” experiences, helping me to sharpen my skills and foster a common sense approach to safety matters. There's always something different to give advice on.

Director, Brand Enhancement Department

As a consultant, I like Impact's programmes because every one of our projects could make the participants think deeply about their issues in the workplace, and move forward for their business success. I am excited when exploring a solution for my clients' current and future business challenges. Besides my job, I like cooking, travelling, fine arts, musicals, Japanese KABUKI, opera etc.

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.

In the last 25+ years I’ve worked with many great organisations and love being able to bring a breadth and depth of experience to my programs. I currently regularly travel across Asia consulting for clients and looking after our great people. I'm described as an Energiser Bunny, I bring energy into everything I do, even if I'm stepping off a 12-hour flight! I recover by spending time with my family and exploring the wilderness in NZ with a fishing rod.

Yoshinobu andHosoki(Hosshan)
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 rely on both my unbridled curiosity and appetite for knowledge and exploration in my pursuit for continuous improvement. As an ambassador of the Impact brand, I harness this mindset to work effectively with my colleagues to increase our brand awareness and build mindshare in the marketplace. In my spare time, you can find me in the mountains skiing, hiking, and fly fishing with my wife and hound dog.

I am happy to be responsible for creating and implementing new solutions as well as taking care of our clients and delivering adventurous programs. I see my purpose as working with people to help them be more aware of their power and inner wisdom and therefore to make our organisations and communities stronger. I get my energy from time with my gorgeous family, biking, reading in a hammock, listening and dancing to the music.

Support

I was an associate for Impact for 21 years before becoming part of the full-time team. I love the sense of fun, friendship, camaraderie and the way Impact works. Oh, by the way I’m on the Technical Support Team – ropes and boats, programme design and logistics and lots of other things too. I love my job, get loads of out of it, meet lots of amazing people and learn new things all the time – how lucky am I?

Mario GianAndrea, Impact Italy
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!

Operation and Programme Manager

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. I appreciate what I have rather than what I don’t have. Photography has been my passion since I was young! I love capturing people’s expressions, emotions and feelings. I use my photos to tell stories of myself, amazing people that I’ve met and inspiring places that I’ve been to.

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.

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.

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!

I joined Impact Italia in 2021 and the magic started happening! Energy, active listening, and continuous exchange are the key elements that characterize my personal and professional life. My purpose here is to design and facilitate ‘ad hoc’ learning solutions that can release transformation and changement regarding the different spectrum of needs that can have organizations. In my spare time I practice dance and yoga, I am travel-addicted and I love to cook to share the results with my loved ones.

Senior Consultant

My big mission has always been building people, teams and managers in the name of passion and authenticity. I do it through my expertise as a manager, as well as by coaching and  mentoring. We have to work so many hours in our lives, my wish is that most people possible would do it in the best way possible. I live in seafront, and I am a sailor. Sea is my key element, especially in winter, when nobody comes.
