East and North Hertfordshire Teaching NHS Trust has appointed Martin Armstrong as its new chief executive, the organisation announced this week. The appointment follows a rigorous recruitment process, and is subject to approval of terms and conditions.

Armstrong has been a leader at the trust for the past ten years, serving as deputy chief executive and chief finance officer. He brings more than 25 years of experience in senior leadership roles across the NHS. Previous roles include positions at North Middlesex University Hospital NHS Trust and Princess Alexandra Hospital NHS Trust. His background is substantially financial: he holds a history degree from Peterhouse, Cambridge, and joined the NHS as an accountant before moving into operational leadership.

During his time at the trust, Armstrong has played a key role in strengthening its performance and financial position, and has been closely involved in driving improvements to services and patient outcomes. That record will have weighed in his favour during the selection process. Internal appointments of this kind are relatively uncommon at NHS acute trusts, where chief executive searches more frequently draw from a national field.

He succeeds Adam Sewell-Jones, who joined the trust in 2022 and will be leaving to take up the role of chief executive at Mid and South Essex NHS Foundation Trust. Over four years, Sewell-Jones led the trust through a period of significant change, improvement and recovery following the Covid pandemic. Trust Chair Anita Day said of the departing chief executive that he had brought clarity, energy and a strong sense of purpose to the organisation.

Armstrong inherits a trust that has made measurable progress on waiting times but still faces the pressures common across English acute providers. East and North Hertfordshire was among the highest performers in the East of England against the 18-week elective treatment target, surpassing 69 per cent. The trust credits its improvement method, the ENH Production System, which involves teams conducting rigorous daily management reviews to identify and address waste and inefficiencies in patient pathways. That performance sits above the NHS England interim target of 65 per cent, though the system's longer-term goal of 70 per cent by March 2027 will require sustained effort.

The more complex inheritance concerns Mount Vernon Cancer Centre, a regional specialist facility currently run by the trust. A public consultation on proposals to move the centre to a new facility next to the new Watford General Hospital ran from January to March 2026, and all responses are being analysed. A final report is expected to be published in June 2026. Subject to the outcome of consultation, the management of the services provided by Mount Vernon Cancer Centre would transfer from East and North Hertfordshire Teaching NHS Trust to University College London Hospitals NHS Foundation Trust. That potential transfer represents a significant operational and governance question for any incoming chief executive. Armstrong will need to manage the service's continuity while the decision is reached and, if the transfer proceeds, oversee a transition involving staff, patients and specialist facilities.

Armstrong said it was a privilege to be appointed to lead his local trust, adding: "I am proud of what we have achieved so far together and grateful to colleagues for their continued commitment and dedication. I look forward to working with our staff, partners and communities to build on our progress and to further improve the care and services we provide."

The trust has not yet announced a date for Armstrong assuming full executive responsibilities, nor has it set out plans to recruit a replacement deputy chief executive. Both are expected to be confirmed in the coming weeks.
