Senior Consultant

I have spent my career exploring, researching, teaching, coaching and practising leadership skills. I love working with individuals and groups to tackle hurdles and develop strategic initiatives. When I am not designing programs, I like to spend time with my son and my husband building forts out of driftwood or laughing with friends in the beautiful pacific northwest.

Coordinator

My food and beverage career began with a bartending job as a student. Working in large restaurants taught me that guest service depends on recruitment and training. After roles as restaurant manager, supervisor, and recruitment and training lead, I focused on employer branding and training programs. To deepen my expertise, I joined Impact Japan, a global leader in experiential learning. I am now developing as an organizational development partner in CSD. I enjoy fishing, hiking, and rugby.

Senior Consultant

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!

Joining Impact in 2024 as an associate, I have had the pleasure of working alongside some incredible humans. I have since joined the full time team as a Program Manager, supporting projects from tender through to delivery and completion, partnering closely with both clients and colleagues.

GM,

Change is my partner in business and life. “Be better” is my inspiration to continue to grow. 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.

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.

Nao andMatsushita(Noa)
Coordinator

'Helping People Shine on Their Own Stage' As a restaurant manager, I wanted to create more than just a place to eat. By drawing out each team member’s strengths and aspirations, I saw the power of a team that values individuality. This led me to study coaching. I later realized that growth also depends on the organization, so I now study organizational development. My goal is to help people and organizations grow together, enabling everyone to shine as themselves and fulfill their potential.

My career has been very weird and challenging so far. I graduated in industrial chemistry, then worked as a research scientist. In 2014 I moved to the energy field as consultant and account manager in charge of technical trainings and management courses. This job lasted 10 years and made me passionate about human resources management. I joined Impact where I can improve my skills as a trainer and facilitator and cooperate with a real great team.

I deal with a lot of internal and external stakeholders to make sure everything is ok with our clients, accounts, invoices and bills!

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.
