Global Lead Solutions & Practice

Over the previous 30 years, I’ve held Impact leadership roles in Asia, America and now globally. My focus is to partner with clients to solve their people development challenges.

Support

I was an associate for Impact for 21 years before becoming part of the full-time team. I love the sense of fun, friendship, camaraderie and the way Impact works. Oh, by the way I’m on the Technical Support Team – ropes and boats, programme design and logistics and lots of other things too. I love my job, get loads of out of it, meet lots of amazing people and learn new things all the time – how lucky am I?

Stuart andKelly
Associate

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.

Consultant

I love why Impact exists, which is to liberate human potential. I love building effective client relationships both externally and internally, the people at Impact are passionate, motivated individuals, and I love working here. I am always out and about, whether it is running around after my niece or walking the fells or working out in the gym, happy, happy, happy!

Martin andSmith
Senior Director - Client Services

I lead the overall relationship with our clients, working closely with them and our brilliant Impact team to build powerful solutions to their most pressing challenges. I’m a bit of an oddity - an Aerospace Engineer by training and experience who, for the last 20 years, has found my passion in helping others thrive at work.  I‘m based in Chicago with my wife, and when not running on the lakefront, I’m probably wrestling with an ornery cat.

For over 22 years, as a consultant, coach and partner, I support leaders, teams and organizations in the process of change. I am an "educational gadget-head.", sharing what I learn with others, because of my passion for people development. Privately my husband and I run “No Kill” fishing-field, building a community of exceptional people.

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.

Global Lead

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. I grew up through Impact as a marketer and love the buzz of building business through brand and storytelling. My other passion is the people and culture here, so this is the ideal combination for me. When I’m not working, I love spending time with my family, enjoying the outdoors and practicing yoga.

Consultant and Facilitator

As a consultant, I hope to be a catalyst for change, helping others to discover what their real needs are. Empathy, curiosity, creativity, organisation and strong sense of duty are the things that most characterise me. I love the adventure and the discovery of travelling, organising outdoor trips with friends in close contact with nature… But also sharing a gin lemon or a barbecue at home is not so bad!

Customer Service and relationship management are my main focus and passion in all that I do. I enjoy thinking through solutions, working in partnership with my clients and team at Impact to achieve the best possible outcomes. I also enjoy developing long lasting professional customer relationships.

Ava andGayowski
Business development & marketing coordinator

I came to Impact as an Intern in 2023 and here I am again in 2025! That’s because Impact is a great place to learn and the people are even better. Impact’s mission to help people learn and grow is something that resonates with me deeply. My educational background is in mass communications with specialties in PR and advertising. I’m the liaison between our marketing and business development team and my job is to enhance our digital marketing and BD function. In my free time you can find me surfing out on the waves (usually wiping out), horseback riding, or behind a guitar and a microphone.

In my different roles I get to lead, mentor, coach, create solutions, and deliver life-changing experiences. I’m lucky to be surrounded by amazing colleagues - whom I get to call friends. I relax by spending time in nature – usually with my loving family but with the occasional solo adventure as well!

Exploring Human and Organizational Creativity 
I have 8 years of experience in the food and beverage industry, focusing on talent and organizational development. Discovering coaching inspired me to apply it in the field, seeing people transform through intrinsic motivation. This led me to join a coaching firm, supporting various industries.  Motivated by the question, "How can individuals and organizations unlock their potential?", I joined Impact to further develop my expertise.  I enjoy playing the drums and held a live performance last year. My motto: "Immerse myself in what I am passionate about while working."

Assistant Manager, Human Development

'Making Work Enjoyable for Children' I’ve spent 17 years in retail, gaining experience in sales, customer service, training, HR, and recruitment. This taught me that business growth relies on people’s growth, inspiring me to pursue my own and motivate children. A key moment was a training program at Impact Co. 11 years ago, sparking my passion for talent and organizational development. As a working mom, I focus on balance—committing to work weekdays and spending time with my toddler daughter on weekends. This balance is key.

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.
