Meet our Ambassadors

We are honoured to have a team of Ambassadors, who are committed to raising the profile of the Social Enterprise Mark and Gold Mark, and why these accreditations are important to their sector as well as the wider world.

We have brought together leaders from social enterprises both nationally and internationally, all of which are striving to create positive social and environmental change. They span multiple sectors, from education to IT, and from business support to healthcare.

Meet our Social Enterprise Mark Ambassadors:

Sona Mahtani

Sona Mahtani

Chief Executive, The Selby Trust

Sona Mahtani is Chief Executive of The Selby Trust, which sells workspace, sports and meeting facilities of all kinds to over 130 grassroots social action and social enterprise organisations, bound together by its motto of “Many Cultures, One Community”.

Sona’s work at The Selby Trust came following a period as a partnership organiser for a funding body, project manager for Off the Streets and Into Work and capacity building networks. She has enjoyed a 30 year career in the voluntary sector with experience in homelessness training and employment, HIV and AIDs support, regeneration, sustainable development, and community asset management.

The Selby Trust employs locally and generates over 75% of its own income amongst diverse communities in areas of substantial multiple deprivation. In this context, Sona says it is a privilege to work as part of communities to make the Selby Centre into a community destination that has a strong and positive future in local plans, in partnership with Haringey Council.

“The Social Enterprise Mark shows we at The Selby Trust are successfully trading as a social enterprise, with well over 50% of our income being successfully obtained through trading, year in year out.

The sector having a kite mark of our own is a way we can identify and recognise each other across a crowded room. The future is bright for local organisations to have a bigger stake in local economic development as they retain authenticity and networks below the radar of large corporations. By achieving the Mark we have a co-opted a dynamic team, constantly finding new opportunities, networking and increasing our potential to foster our movement’s further growth here in the UK and globally.”

Louise van Rhyn

Dr Louise van Rhyn

Founding CEO, Symphonia for South Africa

Dr Louise van Rhyn is a social entrepreneur. She believes the worlds’ huge intractable problems can be solved through cross-sector collaboration and a solid understanding of complex social change. Her approach to change is shaped by more than 30 years of working as an Organisational Change and Leadership Development practitioner. She holds a Doctorate in Complex Social Change and has founded a few entrepreneurial organisations.

In 2008 she returned home to South Africa (after living in Europe) and started Symphonia for South Africa (SSA), a social enterprise with a purpose to mobilise active citizenship around the significant social issues facing the country.

In 2010 she launched Partners for Possibility (PfP), an innovative nation building and leadership development process for business and school leaders. Business leaders develop their capacity to lead in a complex and unfamiliar environment by becoming a co-learning and co-action partner to a school principal. The focus of their partnership is to lead positive change in an under-resourced school.

So far more than 1,700 leaders across South Africa have benefited from the programme and they’ve won many national and international awards for their innovative approach to enabling business leaders to make a significant contribution in education while developing their leadership skills. Participants report that they learn more about leadership from working with a school in an under-resourced community than attending a course at a business school.

“Symphonia for South Africa is proud to be the first social enterprise on the African continent to receive the Social Enterprise Mark and we have committed ourselves to encouraging other social enterprises to distinguish themselves by applying for the Mark.”
