Asia Pacific Finance Director

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.

Senior Consultant

I am devoted to applying theory, practical application and innovation to people development. As a lead designer and facilitator with 10+ years of experience, I deliver custom client solutions globally. My insatiable curiosity stays satisfied by reading, researching and exploring the world. I love the culinary arts, and although I enjoy cooking, my passion is simply being the consumer of freshly made, delectable dishes.

I see life as a gift and a journey. I bring in my backpack some of the experiences I had the luck to have: nuclear engineering and 25 years as a manager in various industries in various parts of the globe. And then Impact. I feel excited when I see the very essence of situations emerge: in individuals, groups, communities, and organisations. I am fond of endurance sports and am a passionate soul explorer.

Assistant Manager, Planner

Working as a planner at Creative and Marketing Department since 2019. Before Impact, my career was mainly on the position of sales and marketing at the bank and advertising agency. My focus is on the capacity building for both individual and team. Virtual team building is one of the fatal themes because I am working as a full remote member. I love traveling around the world with my backpack and enjoying beautiful local delicacies!

Consultant and Facilitator

I joined Impact Italia in 2021 and the magic started happening! Energy, active listening, and continuous exchange are the key elements that characterize my personal and professional life. My purpose here is to design and facilitate ‘ad hoc’ learning solutions that can release transformation and changement regarding the different spectrum of needs that can have organizations. In my spare time I practice dance and yoga, I am travel-addicted and I love to cook to share the results with my loved ones.

Head of Learning Tech

I love both learning and technology, so leading Impact’s learning tech R&D is a fantastic gig. Technology can sometimes feel in conflict with the humanity we seek to serve, but thoughtful application of tech immerses us in challenging experiences, brings us closer together and helps us to learn the most important, most human skills. My approach to learning tech (and life, for that matter) echoes Impact’s practice: experiential and human-centred.

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.

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.

Program, Manager

As a Program Manager at Impact, I get to utilize the communication and organizational skills gained from my 6 years of customer service experience and owning my own business. My favorite aspect of the role, is seeing a program be designed and developed over time, come together in the end. In my free time, you will find me cooking, hiking, painting, or playing with my dogs!

Experiential Solutions Specialist

With over 20 years at Impact, I've contributed to the design and delivery of over a thousand programmes. And what if the secret of success is to continue to refine something even if you've done it dozens of times? Outside of work, I like gardening and interior design. I live on the crest of an extinct volcano, with the Mediterranean Sea to my west. After sunset I keep fit by jogging around a golf course.

Gavin andShaw
VP of Finance

Leading the US finance department includes guiding my team, considering new ways for increased financial success, keeping the team financially informed and ensuring accurate reporting. I have a business/accounting degree and 15+ years experience as a CPA. I see myself as a finance skilled business partner rather than an accountant. I love spectator sports, food, wine, whisky, binge watching TV, travel, wood burning open fires and being outside in the fresh air.

I consult with our customers to understand their business aspirations and challenges before recommending a learning solution that is going to exceed their needs. I maintain close relationships to ensure they receive the best possible service. I work across all market sectors and levels; however, I'm particularly passionate about graduate development. Out of work, you’ll find me up a mountain attached to either a rope or a pair of skis.

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.
