Following an appointments process, Katie Fisher has been appointed as the new interim Chief Executive Officer for North Central London and North West London, taking a secondment from her substantive role as Chief Executive Officer at South West London ICB.
This will follow Frances O’Callaghan’s planned departure on 31 January.
Katie will join the organisations on a nine-month secondment from her current role as CEO of South West London ICB.
She will oversee the launch of West and North London ICB, which will come into effect from 1 April. It will be the largest ICB in England, strategically commissioning services for 4.5m Londoners across 13 boroughs.
Katie brings with her a wealth of experience which will help support and guide the organisations during this important period. A nurse by background, Katie has more than two decades of senior leadership experience within the NHS, charitable organisations, and the private sector. Her previous roles include being Chief Executive Officer at Ashford and St Peter’s Hospitals, and at West Hertfordshire Hospitals NHS Trust.
Mike Bell, Chair of North Central and North West London Integrated Care Boards, said: “I am delighted that we will have the benefit of Katie’s experience and leadership to take us through this important phase for North Central and North West London, and the launch of the West and North London Integrated Care Board from April.”
“I’d also like to thank Katie for the fantastic contribution she has made so far, in the past year at SWL.”
Katie said: “Since joining NHS South West London ICB, I have been endlessly impressed by the commitment and professionalism of the team and the partners we work with across South West London.
“I am proud of the progress we have made together on setting South West London on the path to a more financially sustainable future, with our strong clinical, operational and financial performance during 2025/6 and our solid submissions for this year’s planning round and the emerging work of our clinically-led Strategic Plan. I would like to take this opportunity to again thank everyone at South West London for the warmth and support over the last year.”
“I’m really pleased to be joining North Central and North West London at such an important point. I look forward to taking forward the merger and establishing the new West and North London ICB as a robust, progressive and impactful organisation, which is really making a difference to the lives of people across West and North London.”
Mike Bell added: “I’d like to again thank Frances O’Callaghan for her fantastic contribution. We will miss her greatly, but she should be very proud of all she has achieved for the residents and communities we serve in North Central and North West London.”
The appointment of the permanent role of CEO for West and North London ICB will follow a process expected to take several months. Updates on this will follow in due course.
