Consultant & Sales Hub

Since I've joined Impact, I feel like my professional development grew exponentially. I feel very empowered by the company and by the values we bring each day into work. My goal is to learn how to best support our clients in every step of a consulting journey, as well as my colleagues, bringing a real change to the process. As a way to recharge I love to take long walks with my dog. My favourite sport is to hang out with friends, especially if in foreign countries!

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.

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!

There's always something different to give advice on.

Simon andWagstaff
Senior Consultant, UK

I joined in 1982 when the company was two years and totalled four people. I have had the great privilege of what seems like two parallel careers - helping to build and develop our business and working with clients to help them do the same with theirs. I love the variety of my role, that at Impact personal talent is more important than hierarchy, and that we have never waivered from our vision to make a positive difference in the world, through leadership development.

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!
