Sam has 15 years of experience working in and with the NHS across the UK, developing and delivering new community-led service models to aid collaboration and innovation.  In 2019 she was invited to share her work in the NHS in Wales by TEDx Aberystwyth.

As co-founder and MD of Yma, her role is to bring alive our purpose – to create the conditions where primary care in Wales can thrive now, and for future generations.

Sam is also a passionate advocate for renewable technology and an electric vehicle enthusiast, seeking ways to accelerate progress in this area at a local and national level.

Sarah’s focus is on connecting the journey of Yma to the wider world, ensuring we support people to live better lives.

She looks to develop new partnerships, collaborations and opportunities to further our purpose.

Julia is a post-doctoral chemist with a background in lithium-ion battery materials and teaching.  

Julia joined Yma in 2020 and is leading our project management function. The project management team takes on a variety of projects both external and internal, some of which are on our Projects page. We are always interested in doing new things, or learning how to do familiar things better.

Julia enjoys finding creative solutions to problems, playing with spreadsheets, and illustration.

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.

Kari comes from a background of working with children with developmental delays or disabilities and their families. She joined our team in September 2022 as Office Administrator and has since taken on the role of Project Support Officer. She brings her experience of working as part of a multi-disciplinary team and a passion for helping underserved and vulnerable communities.

Kari's ideal pastime is reading and writing poetry, but in reality, she spends a lot of time building with and deciphering Lego instructions and volunteering as Responsible Individual for the playgroup her children attended.
