Patient constituency

  • Devon Allison: re-elected July 2016

    Devon AllisonI have a master’s degree in finance, and have worked in the communications industry. My volunteer work has been mainly with children, as a reading tutor and a school governor in Lambeth primary schools.

    I'm interested in how children’s experience of hospital can be made as happy as possible.

    Having benefited from excellent care, I hope to contribute to efforts to improve patient experience at the great hospitals that serve me, my family, and my neighbours.

  • Heather Byron: elected July 2016

    Heather ByronWith a career business consulting, I have supported many organisations develop strategies, overcome challenges and deliver customer-focused services.  I previously chaired The Children’s Society fundraising committee and bring a mix of skills, experience and a strong drive to all my roles, which I execute with focus and passion.
  • John Knight: elected July 2019

    John Knight, member of the Council of GovernorsI have recent experience as a senior Governor at another large London NHS Trust - I chaired the nominations and remuneration committee - where I gained knowledge of London NHS politics and finances.

    My professional experience is directly relevant to the role of Governor. After working at the Department of Health, I was a main board director at Leonard Cheshire Disability, and I have wide experience of health and social care matters – the latter being vital to a successful NHS. I was on the board of a London Primary Care Trust and held board level positions on national regulatory agencies.

    I am committed to meaningful and active engagement with patients and staff, evidenced in my previous governor role where I led work on effectively learning from complaints - avoiding making repeated mistakes and telling patients what we had learnt and done.

    I want to form greater proactive collaboration with the many diverse communities Guy's and St Thomas' Hospital serves as I believe this is vital in understanding patients' needs and refining services to meet cultural requirements and expectations – I am a keen advocate of diversity and inclusion being central to all practices and policies.

  • Betula Nelson: elected July 2019

    Betula Nelson, patient governorAs a long-term patient of the Trust I have built a strong respect and trust in its functioning and staff.

    In the last eight years it has made a difference to my life and I feel a kind of affinity to the organisation. I am quite excited by the development of its new cancer centre which deserves all the support it needs.

    I have a long history of connection with the health service as I worked as a psychiatric social worker for many years. I was a part-time senior social worker in the early 2000s in the South London and Maudsley NHS Foundation Trust, a sister trust to Guy's and St Thomas', of which I am a member.

    I have sound knowledge of patient care and the values which are essential for the delivery of holistic care alongside of the medical interventions. I am able to view patient care from both a staff and patient perspective.

    As a retired person I have time and energy to contribute to the system and am conscious of my civic duties. I feel that the combination of the above experiences and qualities enable me to work as a governor and help improve the work of the Trust.

    I am a committee member of the Law Society's lawyers with disabilities division. My most recent achievements include a successful campaign to persuade the Law Society to go purple in November and December this year in as part of the Disability Confident campaign.

    I am honoured to have been listed in the 2018 Power 100 List of the most influential disabled people in Britain by the Shaw Trust. My interest as a patient governor, is to review and improve the experiences that all vulnerable people may face.

  • John Powell: elected July 2019

    John Powell, member of the Council of Governors Health management rightly heads the public agenda, and I want to help in guiding the Trust toward delivering a world-class health service. My senior management background entailing public accountability and achieving statutory performance targets enables me to offer unique oversight as a Governor.

    My experience as a patient, at one time seriously ill, has given me insight into the Trust's 'front line', furthering my desire to be involved in guiding and developing its future. Over many years I have seen first-hand how the absence of adequate health services can negatively impact on communities and the social environment. I want to help in ensuring against just that.

  • Mary Stirling: elected July 2018

    Mary Stirling, patient governorI am a qualified and experienced teacher with a background in education and health.

    I was an Oxleas governor for 6 years and a school governor for 3 years.

    Many years ago (1976!) I worked at Guy’s hospital so I feel that I already have a connection with this great hospital.

    I have recently used both Guy’s and St Thomas’ services and would like to give something back. I feel that I have the passion, skills and experience to make a positive difference. 

  • Simon Yu Tan: elected July 2018

    I wanted to be a Governor at Guy's and St Thomas' Hospital because I have been a patient here a number of times since I moved to London.

    With ever increasing complexities and issues arising, I am able to bring over a decade of trustee board and non-executive director committee experience to this governing body, as well as being able to better champion the voices and needs of parts of our local community that can be lacking.

    I am extremely excited about taking on this role, I love living in Lambeth and the different pockets of communities that all co-exist and intertwine with each other, and the opportunity to ensure we are best serving them usually at their biggest time of need is truly humbling but exhilarating.
