Zoe Peden
We have a founder health clause in our term sheet at Ananda where we emphasise the importance of the use of coaches for their wellbeing and performance. We brought Rebecca/Wise Sherpa in to explore the issues of what founders especially female founders need to thrive and the position/role coaching takes in the process. Very timely and just what we needed to provide an optimal service for our founders
Will Goddard
Rebecca brought an informed, objective perspective to my situation and coached me through a challenging transition in my career. Her approach was at once grounded in research and evidence, as well as highly tailored to me as an individual. She asked the right questions, listened and reacted sensitively to my answers, and guided our sessions in a way that led to clarity I had not been able to achieve alone. I would highly recommend her as an executive coach.
Jane Theaker
Rebecca is a really inspirational coach. She helped me to see the various dynamics on my board and within the company through a different lens. She enabled me to approach my CEO leadership in an authentic way and to communicate, ask the right questions and make the right moves at the right times. She also has a great grasp of female leadership and the gender differences. I would heartily recommend her as a superb CEO coach.
Donna Johnston
As an EY accredited coach, Rebecca was a highly valued member of the EY coaching team who consistently received strong feedback from her coachees. Rebecca coached EY professionals in EMEIA and globally across a range of key transitions including new partner, partners on the Harvard Business School Leadership programme, maternity and parental leave, as well as coaching high potential teams (incl the EY Next Gen programme challenge) and women in leadership. In my experience heading up EY’s EMEIA TAS coaching centre of excellence and as an experienced coach (with PhD in Coaching), I believe Rebecca to be amongst the most talented of executive coaches with whom I have had the pleasure to work with.
Marieme Jamme
I got to know Rebecca in her previous work at EY (Ernst & Young) where she invited me to speak at a meeting focused on G20-W20. Rebecca was instrumental in the creation of my organisation iamtheCODE and genuinely helped us with our strategy and mentoring processes. She gave us her time and really supported us. I was so impressed with her professionalism and vision to bring digital transformation into the lives of women and girls. Her drive to accelerate the power of women in business, government and entrepreneurship attracted me to work with her on many occasions. I highly recommend Rebecca as a mentor.

Brenda Trenowden CBE, CFA, CCMI
When the 30% Club decided to kick off its highly successful cross company mentoring scheme five years ago, Rebecca was appointed as the programme lead to work with a small group of our corporate members to design and implement the pilot of the scheme. She demonstrated her strategic yet practical approach by developing with our members a programme that was able to scale and sustain over time through the use of technology but also by building trust based relationships through her well honed influencing and leadership skills. The programme was founded on a reciprocal model with all time given by company leads, mentors and mentees on a pro-bono basis. What makes it a unique programme in the corporate space is the breadth and volume of women in the corporate pipeline who have now received high quality mentoring with 2346 mentees and mentors and 107 organisations having taken part. Rebecca was instrumental in getting the programme off the ground and ensuring it was built for success.
Joanna Santinon
I worked with Rebecca at EY in her capacity as the global co-lead on EY’s Women Fast.forward. In particular, we collaborated on EY’s Entrepreneurial Winning Women and it’s launch across EMEIA as well as the 30% Club cross company mentoring scheme aimed at mid career women.
For the latter, she led the pilot of the cross company mentoring scheme in 2013 which EY created and then provided to The 30% Club to run. Rebecca turned the vision into reality – she worked across organisations using her great strategic project management and interpersonal skills to deliver on time and within budget. She really drove the programme forward in terms of use of technology and gaining successful engagement and buy-in of organisations. Rebecca was also laser focused on the dual task of running the pilot but really looking at how it could be scaled up and move to a BAU model.
The programme today has seen over 2000 female mentees benefit from a cross company mentor from some of the biggest brands in the FTSE100 and it runs in largely the same way as the model established by Rebecca five years ago
She is a pleasure to work with and should be really proud of the lasting legacy she created.
Emma Avignon
Rebecca is a great strategic thinker, innovator and collaborator. Her passion for diversity, in particular women in the work place is evident in the connections she makes and innovation she brings to her work. Rebecca is an inspiration to those she works with. She is always “in the know” and has good ideas that she sees through into actions to create positive change around all her work.

Dr Ghina M. Halabi
I invited Rebecca to design and chair a panel about female entrepreneurship on Enterprise Tuesday, a programme offered by Cambridge Judge Business School’s Entrepreneurship Centre. Rebecca’s expertise, network, insight, and professionalism guaranteed an expert lineup of speakers. She facilitated the discussion with wonderful clarity, gravity and structure. The panel discussion kept the audience engaged and the feedback was phenomenal. Every attendee left inspired or having learned something new. It’s a great pleasure to work with Rebecca whose guidance and insight I have also sought on multiple occasions. I highly recommend her services.
Stephan Kuester
Having worked with Rebecca for many years and in a variety of functions at Ernst & Young Global she has always impressed me with her desire and motivation to tackle difficult organizational problems and to effect required change management projects of frequently large and complex scale. Rebecca’s analysis of organizational issues that we need to address as an organization to deliver continuously improved client service worldwide has always been sharp and to the point. She impresses with solid and thorough analysis and she sees through respective project delivery effectively and timely. She is great in taking teams with her and she is strongly respected as an adviser and consultant to senior management. As a person she stands out in combining sharp business analysis with great social skill and in depth understanding of human behaviour – the latter providing to be increasingly important to maintain and build the trust of all stakeholders involved in organizational change.
Charles Wilson
Rebecca worked with us to design, develop and moderate our Penna London Tech week event on Talent and AI. Through Rebecca’s network, we were able to attract an excellent keynote speaker and build a first class panel developing some powerful outcomes through the event. We were delighted with the results! As a result, we would strongly recommend Rebecca as both a facilitator and consultant if you’re thinking of organising a client facing or internal event. She not only has great gravitas but is able to engage the audience in a highly interactive way with impact.
Sarah Thorne
Rebecca designed and facilitated a workshop for us to explore our business strategy exploring different options on how to grow and future proof our business. She quickly got to the root of what we do working together with us. She created a session that allowed us to explore ideas whilst keeping us on task to ensure we created some actionable outputs. She drew on her wealth of expertise to help guide and shape the session, giving us key building blocks from which to progress. She has a collaborative, yet decisive style and I am looking forward to working together again soon.
Fleur Bothwick OBE
I worked with Rebecca for a number of years and watched her knowledge and experience grow in the Diversity and Inclusion space, particularly with gender. I’ve seen Rebecca develop and execute high profile, successful cross company and market facing programmes on a ‘shoe string’, use her EI to influence multiple stakeholders at different levels of our organisation and develop and deliver innovative solutions, often working cross culturally. She is tenacious, resilient and best of all, can deliver all of the above with an infectious sense of humour.
Elizabeth Isele
I have worked with many, many leaders throughout my 50+ year professional career, and I can say without any reservations whatsoever that Rebecca stands in the upper echelons of those who have inspired me. Her knowledge, expertise, energy and generosity – not to mention her joie de vivre – as she connects like minds and resources is the antithesis of traditional corporate gridlock. Her innovative and entrepreneuring mind, especially in regard to the economic empowerment of women, is second only to her ability to put those innovative thoughts into action, opening doors and creating opportunities for women worldwide. It is both a pleasure and a privilege to work with such a consummate and compassionate professional.
Stephane Dubois
I started working with Rebecca three years ago as EY and Chatham House embarked on a collaborative journey with W(women)20 to tackle gender inclusiveness in G20 countries. I was immediately impressed by her profound knowledge of the issues to be addressed as well as the strategic thinking, energy, commitment and passion she brought to the project. She is wonderful to work with; a great, reliable, supportive and responsive partner who is an incredible asset for the project. I sincerely hope to be able to continue working closely with Rebecca on the Gender and Growth Initiative for years to come!
Margot von Aesch
I was able to benefit first-hand from Rebecca’s very impressive professional skills and extensive network in the world of diversity when we set out to organise an event for some of our senior female clients in April 2016. She helped us to 1) decide on the appropriate format, 2) identify potentially interesting and relevant subjects for an audience of women in the financial industry and 3) short-list relevant guest speakers. She even committed to stepping in as back-up when logistics threatened the on-time arrival of our designated speaker! Our networking evening was a great success, and Rebecca’s contribution immeasurable. She has a wealth of ideas and a depth of connections which I would gladly make more use of in the future.
