I am a highly experienced Accounting and Financial Management professional with expertise in problem solving, business communications, project management and customer relationships. I’m an enthusiastic leader, successful in liaising across all levels, handling confidential information and managing multiple priorities. I enjoy attending live events; cheering on my favourite sporting teams, watching my friend’s rock band, and supporting my daughter’s dance team.

Lisa Felloni
I provide inspiring opportunities for leaders to explore possibilities in expanding sustainable business and organisational development. As a staff support manager I have been leading operations such as talent acquisitions. Supporting others and organisations to expand their full potential is my passion. I enjoy ensuring we have a unique workplace where we can maximise potential and strengths. I love climbing mountains, hot springs and good organic foods.

Hannah Reeves
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.

Warangkana (Lek) Posinsomwong
As an Account Director with Impact, I’m able to leverage my ten years of Business Development and Account Management experience. I thrive in environments where I am able to develop and uncover new opportunities with partners and businesses. Most of all, I am a people person and love building trusting relationships. In my spare time, you will find me spending time with my husband, two boys and our dog.

Diana Fritz
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!
Gianna Ruffo
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!

Steven Nishida
After living in France and working in the ski industry for 13 years, I decided to move back to the UK, joining the Impact Project Management team. I work on several major global client solutions across industries such as insurance, pharmaceuticals, sportswear and automotive. I build strong working relationships, both internally and externally, to support teams through solution design to delivery.
Gabrielle Thorpe
I co-founded Impact in 1980 to explore adventure and experiential learning in people development. It worked! We now inspire and develop people worldwide. Shared values, a common purpose and a spirit of adventure bind us together. With over 200 colleagues working in the UK, Europe, America and Asia Pacific, we have a solid reputation for enabling clients to build leadership capacity and navigate complex change. To stay grounded, I rear rare breed cattle and sheep.

David Williams
I am responsible for developing great client relationships and ensuring the successful rollout of our Australian programs. With a background in account management, content design and coaching, I love providing opportunities for people to see and realise their own potential. Collaborating to enable learning and development at the organisational level is a dream. When I’m not at work, you can find me teaching yoga or out in nature with my husband.

Charlotte Messervy
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.

Delfino Corti
Sum myself up in a paragraph? There’s a challenge! And maybe a good starting point. I like challenge. I like the challenge of grabbing attention with interesting, useful and relevant marketing. From a new website or re-brand to a sell-out festival, for me it’s all about customer first. I like a physical challenge too, and the challenge of how long I can last without listening to music!

Lou McDonald
I enjoy using my strengths in operations management to bring organisations into the chaos and to connect people with resources. I look forward to supporting the team from behind the scenes to execute the programs successfully and meaningfully. In my personal time, you will find me traveling, cooking, event planning, reading, and involved in theatre and film productions.

Shiwali Daryapurkar
I'm passionate about helping those around me grow and develop. I encourage my team to bring themselves into everything they do. Our diverse backgrounds, experiences and perspectives help us partner efficiently and effectively with colleagues and clients. As a traveller at heart, I’ve visited 31 of the 50 US states, 14 countries and 8 Caribbean islands. I love experiencing new cultures, enjoying the great outdoors and trying local cuisine.

Carrie Fritz
I’ve had a passion for enriching lives through deeply practical experiential learning, and immersion in adventure around the world for most of my career. As a British Army officer, expedition leader, leadership consultant and executive coach I’ve had the enormous privilege to facilitate learning experiences for others in over 40 different countries. My greatest gift - apart from my wife and kids - doing the work I love!
Clive Barrow
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.

Doug Greenhough
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!
Arianna Bianchi
As a resourcing manager, I drive business processes to improve efficiency, maintain quality relationships with consultants and ensure the best strategic fit is sourced for our clients. I love that we operate in a fast-paced environment, always requiring you to be one step ahead, and I value the connections we have globally. Outside of work, you can usually find me at my piano, brushing up on my very rusty repertoire.

Ruth Ollis
I am an enthusiastic trainer and consultant, keen on applying theory, practical application and innovation to the development of others. I have been working in the learning and organisational development since 1996 and joined Impact in 2019 as account, lead designer and facilitator. I pride myself on my original, inclusive and enthusiastic style.
Stella Privitello
My Impact career began in 2003 with a passion for adventure as a learning experience. Throughout my years at Impact, I've worked with incredibly talented colleagues, clients and people at all levels of leadership seeking to thrive at work. I love helping others make a difference in the world, am a bit of a science geek, a keen runner and love being a Dad to my three young boys.

Scott Rose
Digital Designer at Zinco/Impact. I am based in Windermere, UK.
Johnny Walker
This is my return to Impact after 11 years as Sustainable Business Enabler. During my absence, I had my own journey to different countries to explore different ways of education. Established a volunteer organization in 2016 and since 2020, supporting Rohingya children in refugee camps became our main activity. Only people can change the world for a better place. Education is my lifetime passion and a continuous lifework.
Mayumi Chokki (Mayu)
I support delivery of high quality, safe and challenging programmes and keep the operations infrastructure in a safe and workable condition. I have been lucky to have worked in some amazing places around the world with some amazing colleagues and participants. Working from Base still takes some beating though! When not working I enjoy having adventures with my family, exploring the Lakes and keeping fit by running, climbing and riding my Cyclocross bike.

Tim (Lofty) Lofthouse
I love the Lake District, working with people and my role as an account manager. I build and maintain strong, long-lasting customer relationships and ensure successful solution delivery specific to the individual needs of my range of clients. I endeavour always to exceed expectations and go the extra mile in all aspects of my life. Outside of work, I love to travel, food and rugby - which I can normally combine for a perfect weekend away!
