Simon Wheatley, Impact International
UK
Simon andWheatley
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.

Yukiko andAsano(Coco)
Client Partner

I have worked at Impact Japan since 2015, coordinating the delivery of programmes. I support our consultants and delivery operations. What makes me happy is seeing my colleagues, clients and participants smile, as my job is supporting them. My hobby is collecting Starbucks Coffee mugs from around the world, although I don’t drink coffee personally!

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'm based in Thailand, a country of beautiful islands, good food and nice people. I have a lot of fun working with people around the world. 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.

I joined Impact 20 years ago and have worked in many different roles as a consultant, general manager, coach and business developer from offices in Europe and Asia. In my current role, I am responsible for supporting businesses in Poland and Central Europe, and I am also co-creating transformation solutions with clients.

I manage project set up and use technical skills such as abseil belaying. I have a teaching licence to teach PE. Now I enjoy working using my body, so I love to do exercise and jogging, swimming, gymnastics, and most outdoor things!

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.

I’ve worked in learning and development since 2000 across a broad range of sectors. I always enjoy the challenge of identifying participants needs and matching the environment, task and conversation to help create meaningful and long lasting learning. Outside of work, you'll find me exploring the outdoors with my family, be that on bikes, in canoes, rock climbing or even exploring underground; we love the challenges that adventure brings to our lives.

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!
