Alison Twycross

Alison Twycross


Alison has been living with Long Covid since March 2020 but is doing her bit to advocate for UK healthcare workers with Long Covid including as joint-Chair of the Royal College of Nursing’s Long Covid working group.


Alison has nearly 40 years of experience in nursing as a practitioner, researcher, and university educator with a passion for children’s nursing and developing leadership potential in the nursing community. She also has extensive experience in researching children’s pain management. A vocal advocate, writer and blogger, Alison addresses key policy issues and often challenges the dominant discourse. Alison is passionate about ensuring evidence is used in clinical practice as well as in nurse education. Since 2010 Alison has been the editor-in-chief of Evidence Based Nursing.

In March 2023 Alison became an Honorary Associate Professor in the School of Nursing and Midwifery at the University of Birmingham.

Long Covid Advocacy

In January 2022 she founded Long Covid Nurses and Midwives UK but stepped down from her role with the group in October 2022. She continues to campaign and advocate on key issues and remains a member of Long Covid Support and the Long Covid Support Employment Advocacy Group. Alison also enjoys working with colleagues from Long Covid Work.

Adrian Powell

Deputy Chair/IT Lead

Adrian’s career as a captain for the UK’s flag carrier airline came to an end after 32 years following a bout of covid in September 2020. Having previously taught himself how to create websites and databases to while away the time spent away from home he now finds himself with plenty of spare time on his hands. His cognitive issues and headaches of long covid means everything takes much longer than it should, but it does get done eventually.

Adrian initially got involved with the PilotsTogether charity, which was set up to help pilots who were made redundant at the beginning of the pandemic, and he saw the parallels with healthcare workers who were also losing their job. He is now looking after the IT side of SHH-UK and helping to drive forward with their aims and aspirations.

Michaela Barnard


Michaela is a children and young people’s nurse and an academic at a UK university. After 20 years in clinical practice where she cared for children and families’ palliative and bereavement needs in an ICU, Michaela moved to an academic setting. She undertook a PhD in neonatal palliative care and she continues to teach the next generation of children and young people’s nurses.

Michaela found herself seriously ill in hospital with COVID-19 pre-vaccine and watched healthcare colleagues work like they were on a battlefield, short-staffed yet delivering excellent care. She has been living with Long Covid since December 2020. Michaela has a good employer who has provided a disability support plan with reasonable adjustments so that she can stay in work. This is the minimum that healthcare workers who acquired Long Covid during the pandemic should receive. Therefore, Michaela is passionate about advocating for and aiding those who are unwell and out of work because of their commitment to others in this context.

Millie Powell

Trustee - Social Media Lead

Millie is an editor-turned-project manager working in biology research funding in the UK. She graduated with an MSci in Applied Biological Research from the Royal Veterinary College in 2019 and has since developed key skills in the field of academic publishing, including the wide world of social media. She also volunteers on the Board of Directors of the Journal of Young Investigators, a peer-reviewed journal for undergraduates run by undergraduates, where she acts as a mentor for the current executive board.

Millie’s dad has had Long Covid since 2020 and so she has witnessed first-hand the long-lasting effects that can linger following Covid infection. Millie joined Supporting Healthcare Heroes UK in March 2024 and hopes to help spread the word about the work of the charity, and help care for those who cared for us during the pandemic.

Dame Sarah Cowley DBE

Trustee - Safeguarding Lead

Sarah retired on health grounds in 2012, after a career that started in nursing in 1964. An interest in public health, inequalities and social injustice led her into health visiting in 1980, and a move from the NHS into academia in 1992. That provided many opportunities for teaching across community practice, research, publications and international travel, culminating in the award of a Damehood in 2013 for services to health visiting. She continues to stay in touch with former colleagues and the profession through her work with the Institute of Health Visiting, as a patron for a specialist home visiting programme and through occasional writing and editing.

New interests in retirement include living close to my family and grandchildren, editing for a ‘citizen journalist’ website, walking the dog along the beach and in local green areas. Having been so long retired at the start of the pandemic and being declared ‘clinically vulnerable’ meant she was protected from the worst effects of Covid, but also frustrated at being unable to help when so much was being asked of former colleagues on the front line. She is pleased to turn her passion for social justice to help support those affected by Long Covid, which is a particularly unfair burden faced by healthcare workers who contracted the disease through clinical practice.
