Some clinicians follow a direct path into their specialty. Others take a longer route, accumulating experience across multiple institutions and disciplines before arriving at a point where everything converges into a clearly defined surgical identity.
Dr. Matthew Erritty belongs to the second group. He is a Consultant Obstetrician and Gynaecologist specialising in advanced laparoscopic and robotic surgery and endometriosis, based at Ashford and St Peter’s Hospitals NHS Foundation Trust and the Centre for Endometriosis and Minimally Invasive Gynaecology (CEMIG).
His career began in 2009 as an Anatomy Demonstrator at Brighton and Sussex Medical School, a role he held from August 2009 to August 2010. This early academic foundation provided a deep structural understanding of human anatomy that would later become central to his surgical work in minimally invasive and robotic procedures.
Eight Years of Progressive Training Across Leading London Institutions
Dr. Erritty’s postgraduate training was undertaken across several of London’s and the South East’s major NHS trusts, each contributing a distinct layer to his clinical development.
He began as an ST1 at Guy’s and St Thomas’ NHS Foundation Trust (2012–2013) before progressing to Kingston Hospital NHS Foundation Trust (ST2–ST3, 2013–2015). He continued his training at Epsom and St Helier University Hospitals NHS Trust (ST4, 2015–2016), returned to Kingston Hospital as an ST5 (2016–2017), and completed his final specialist training years at Ashford and St Peter’s Hospitals NHS Foundation Trust (ST6–7, 2017–2019).
It was during this final phase that his focus on advanced laparoscopic surgery for benign disease and complex gynaecological conditions was formally consolidated, alongside advanced labour ward practice. This multi-institutional training pathway across Guy’s and St Thomas’, Kingston, Epsom and St Helier, and Ashford and St Peter’s represents a broad and structured exposure to high-volume, complex gynaecological care.
The Transition into Consultancy and the Making of CEMIG
In June 2019, Dr. Erritty was appointed Locum Consultant Obstetrician and Gynaecologist at Ashford and St Peter’s Hospitals NHS Foundation Trust, before taking up his substantive consultant post in September 2019, which he continues to hold.
His total clinical association with Ashford and St Peter’s now spans over eight years and nine months, including both training and consultant practice. In parallel, he joined the Centre for Endometriosis and Minimally Invasive Gynaecology (CEMIG) in June 2019 as a Consultant Gynaecologist and Robotic and Laparoscopic Surgeon. This role remains central to his clinical identity.
CEMIG functions as a specialist centre focused on endometriosis and advanced minimally invasive surgery, reflecting Dr. Erritty’s long-standing commitment to treating these conditions as dedicated subspecialties requiring focused expertise, infrastructure, and surgical precision.
Leadership and the Clinical Director Role
Between March 2022 and December 2025, Dr. Erritty served as Clinical Director of Obstetrics and Gynaecology at Ashford and St Peter’s Hospitals NHS Foundation Trust.
The role involved departmental leadership, clinical governance oversight, and strategic responsibility for service delivery across obstetrics and gynaecology. It required balancing operational leadership with ongoing clinical and surgical practice. Alongside this, he maintained his active surgical role at CEMIG, reflecting the dual clinical and leadership responsibilities he has carried throughout this phase of his career.
Extending Expertise into the Private Sector
Since January 2021, Dr. Erritty has also worked in the private sector as a Consultant Gynaecologist at BMI The Runnymede Hospital in Ottershaw and at Nuffield Health Woking, where he continues to provide specialist care in endometriosis and minimally invasive gynaecology.
These roles extend his clinical expertise beyond the NHS, offering access to advanced laparoscopic and robotic surgical care to a broader patient population across Surrey. Rather than operating as separate professional tracks, his NHS and private work reflect a single clinical approach applied across different healthcare settings.
Seven Years at the Frontier
Dr. Matthew Erritty’s career reflects a structured progression from anatomical education to advanced surgical specialisation, followed by consultant practice and departmental leadership.
From his early academic role in Brighton, through his multi-site NHS training across London and Surrey, to his consultant and leadership roles at Ashford and St Peter’s and CEMIG, each stage has contributed to a consistent focus on complex gynaecology, endometriosis care, and minimally invasive surgery.
At CEMIG in particular, this preparation has been translated into sustained specialist practice over more than seven years.
In a field where outcomes are closely tied to technical precision and depth of subspecialist experience, his career reflects a deliberate accumulation of training, responsibility, and surgical focus that continues to define his work today.
