Yma is a not-for-profit social enterprise, existing to create possibilities for exceptional care for the people of Wales now, and for future generations

The viability and future shape of our health and social care system is being tackled by many different organisations and agencies in Wales.

The lens through which we undertake our work, advocating from grassroots, being open to all possibilities without being tethered to the status quo (even rejecting it where needed) and actively seeking alternative ways for the system to exist, sets us apart.

This makes Yma unique in Wales.

Data Protection Officer

Matthew is the Data Protection Officer ‘DPO’ for Yma. This means that he works with the team at Yma around all aspects of information governance and data security. It is easy to just see this as a security role: Matthew thinks it is more about using information in a way that creates a learning culture and supports innovation, whilst at the same time keeping the promise that we make to our staff, partners, customers and patients to keep it safe.

Matthew has a long-standing connection with Yma, having worked with Sam Horwill when ‘Here’ was founded in Brighton, in 2008, where he is still a Non-executive director and Chief Information Officer.
