Senior Consultant

When asked, "What do you do for work?" it is not uncommon for me to respond, "Light Bulb Moment Technician". I have been fortunate to be filled with such energy through my talent, leadership, and organisational development work. When I am not working, I take my role as Aunt Cassie with my husband, Josh, very seriously! It is the greatest thrill to teach them to ride motorcycles, do yoga, and explore the world.

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.

Akira andMatsumoto(Mikey)
Assistant Manager, Facilitator

With nearly 18 years in the retail industry, I held roles such as sales, store manager, trainer, and area manager. These experiences taught me that when people grow, organizations grow. Supporting others made me reflect on my own growth and whether I still had something to offer. To challenge myself, I moved into a new industry. Now, I work to create training experiences that resonate emotionally and leave a lasting impression—while continuing to grow with my clients.

Support

In support we deliver on programs and manage day-to-day operations and infrastructure. I really enjoy my role as it’s very diverse, one day I am canoeing on Windermere and the next cleaning boots! My favourite programs feature outdoor activities and journeys. People see me as a steady pair of hands and a person who does a quality, professional job. Outside work I keep myself fit and active, and enjoy chilling out with my wife Emma and travelling in our camper van.

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.

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.

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!

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.

'Continuing to "enjoy" life'
My lifelong mission is to continue positively influencing both myself and those around me, while persistently seeking enjoyment.
Throughout my career, I've had various experiences, from utilizing cutting-edge technology in logistics to engaging in gritty tasks. Through these experiences, I've realized the importance of finding meaning and joy in everything I do. Although sustaining this mindset is not easy, I am committed to continuous learning to become a professional to bring a positive impact to people and organisations.

Verity andBellouere
Project Manager

I look after clients from tender, right through to evaluation. Three of my four main clients are global, so it’s about managing time differences too. I am the 'go to' person for many other things as I've worked here since 1991. I'm open, honest and always have an opinion! Questions usually start with “you will know...” I like nothing more that being up a hill in the Lake District or French Alps and camping in Cornwall with family and friends.
