There is a moment in every meaningful career when the role you have been preparing for finally meets the person you have become.. As Sarah prepares to step down from her role as Network Clinical Lead for Biochemistry at South West London Pathology, Sarah reflects on her forty-two year career that began with a serendipitous laboratory placement and evolved into a legacy of connection and collaboration.
A path less planned
When Sarah completed her first degree in Biochemistry and Physiology at Southampton in 1983, she had no clear roadmap for what lay ahead. The opportunity that shaped everything came through her uncle, an ear, nose and throat surgeon, who secured her a three-month locum position in a local hospital biochemistry laboratory, a role that would today be called a biomedical scientist.
That brief placement opened her eyes to a world she had never known existed. In an era when careers advice was sparse, particularly for young women interested in science, Sarah discovered the clinical scientist route and knew immediately it was the path she wanted to pursue. “I’d always loved everything clinical and scientific and this seemed like an ideal career,” she recalls.
In 1984, she secured a place on the clinical scientist training programme at Kingston Hospital, a decision that would anchor her professional life for the next four decades. After two years of training, and a brief placement at the Westminster hospital, Sarah accepted a research post at the University of Surrey in Guildford, which evolved into a PhD exploring factors that affect the glycation of proteins, the process by which glucose binds to proteins in the body, a phenomenon relevant to diabetes management and the measurement of long-term glucose control through HbA1c testing.
Looking back, Sarah describes that PhD as transformative. The doctoral experience taught her self-direction, analytical rigor, and the resilience to see a complex project through to completion. Those qualities, combined with the publication of three papers in recognised journals, equipped her for leadership in ways she could not have anticipated.
Homecoming
The pull of clinical practice proved stronger than the allure of academia. In 1989, Sarah returned to Kingston Hospital as a senior biochemist, rejoining the institution where her training had begun.
The following decades saw her steadily ascend through the ranks. She became a consultant clinical scientist in 2008, head of department for Biohemistry and Immunology in 2012, and clinical lead for Pathology at Kingston in 2013. Along the way, she earned membership of the Royal College of Pathologists in 2005, navigating the rigorous written exams, practical assessments, and viva voce that the qualification demands.
These achievements came alongside raising two children, a reality that shaped both her timing and her perspective. Sarah acknowledgid that her career progression unfolded at its own pace rather than according to any rigid timeline.
For Sarah, the consultant post at Kingston represented more than professional advancement. It was the culmination of decades of relationships built with clinicians, GPs, and colleagues across the hospital. The institutional knowledge she accumulated, understanding the nuances of the culture, the unwritten rules, the key players, proved invaluable when she stepped into broader leadership roles.
During her time at Kingston, Sarah played an active role in point-of-care testing (POCT), initially acting as coordinator being responsible for the quality of testing. Later Sarah was appointed as Kingston Clinical POCT Lead. During this time she helped developed the POCT team and, most significantly, persuaded the Trust to appoint a POCT manager to over see the rapidly expanding use of POCT in the hospital. After the formation of the SWLP network, Sarah was appointed network clinical lead for POCT ?year
Forging the network
In 2014, Sarah was appointed clinical lead for Biohemistry for the implementation of the SWLP network, The network brought together biochemistry services from Kingston, St George’s, and Croydon hospitals, requiring unprecedented collaboration across sites with both clinical and operational colleagues.
It was here that Sarah discovered dimensions of herself she had not fully appreciated.The role demanded communication and collaboration,skills, diplomacy, strategic thinking, and the ability to bring diverse stakeholders together around shared goals. This new position required her to navigate organisational complexity, build consensus and harmonisation of services across 3 sites.
These are the moments that define a career. For Sarah, the SWLP work became “my most fulfilling and happiest time of my career.” The collaboration with clinical and operational colleagues across the network, the shared problem-solving, the achievement of something larger than any individual could accomplish alone, Sarah says ‘ Im really proud of what we have achieved in our Biochemistry network in SWLP. We have met many challenges along the way ,but I have been incredibly lucky to work with and have the support of so many wonderful, dedicated colleagues who have shared the same goal, to provide the a high qualiy and effective Biochemistry service for our patients and medical colleagues in South West London.
Looking back, moving forward
As Sarah prepares to retire, she does so with the satisfaction of having built something lasting. SWLP is established. The clinical leadership is transitioning to capable hands, Croydon Consultant Clinical Scientist Thomas Morris, who is taking over the role of network clinical lead for biochemistry and who, who she has mentored and encouraged. “Don’t be afraid of it,” she advises those coming up behind her, acknowledging the challenges while celebrating the fulfillment the work has brought her.
Her advice to the next generation of clinical scientists is direct and personal: embrace the challenges, because the rewards are profound. The sense of achievement that comes from collaborative work, from solving complex problems, from building connections across traditional boundaries, these are the things that sustain a career over forty years.
A lasting contribution
Sarah’s journey from locum biomedical scientist to network clinical lead has spanned over four decades of transformation in the NHS, from the early days of her career when she was “totally unaware of NHS laboratory jobs” to the complex integrated networks of the present day.
Her legacy is not just in the systems she helped build or the qualifications she accumulated, impressive as they are: BSc, MSc, PhD, FRCPath. It is in the culture she helped create, one of collaboration, mutual respect, and shared purpose. It is in the colleagues she mentored, the relationships she cultivated, and the example she set of a scientist who never lost sight of the human dimensions of healthcare.
“There’s nothing that can replace that sense that you’ve done something really worthwhile,” she says. After over forty years of service to the NHS, and particularly to the patients and clinicians of Kingston and South West London, Dr Sarah Davie can rest assured that she has.
