I have a passion for helping people in organisations perform to their potential. I have spent the past 10 years co-creating solutions to develop high-performance cultures. I work in elite sports and use the transferability of the skills people need in those environments in a competitive business one. I completed my PhD researching Leadership & Well-being in blue-chip organisations and apply this to my practice.

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.

When I’m not working, I love spending time with my family, enjoying the outdoors and practicing yoga.

Mario GianAndrea
President and Founder, Italy

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!
