Guy’s & St Thomas’ Foundation announces today that after seven successful years at the helm, Chief Executive Kieron Boyle will be stepping down on 5th May.  

During his time as Chief Executive, Kieron has overseen significant growth and development, positioning the Foundation as one of the UK’s leading health foundations. 

Recruitment has begun for an interim Chief Executive for a period of 12 months.  The recruitment of a permanent CEO will be undertaken later this year. 

Kieron will be taking on a new role as Chief Executive of the Impact Investing Institute.

The Foundation has also confirmed the appointment of a new Chair of the Board of Trustees, Susanne Given, who has served as a Trustee since October 2021 and who will take up the position from 1st April. 

Incoming Chair of Guy’s & St Thomas’ Foundation, Susanne Given said: “On behalf of the Board of Trustees and everyone at the Foundation, I’d like to thank Kieron for his commitment and dedication to our mission during his time as Chief Executive. The Foundation has made great strides towards building a healthier society during his tenure. We wish him the very best in his new venture.” 

It has been an immense privilege to lead the Foundation these past seven years and be a part of the collective effort that’s essential in creating better and more equal health for all. I couldn’t be prouder of what we and our partners have achieved. I leave confident in knowing the Foundation is in excellent hands, grateful to have worked with such an amazing team, and looking forward to being a continued friend and advocate for the Foundation’s vital work.

Guy’s & St Thomas’ Foundation is made up of a family of forward-looking organisations all focused on investing in a healthier society, built on equitable health for all. 

Achievements during Kieron’s time as Chief Executive include the establishment of our philanthropic arm, Impact on Urban Health, which takes a long-term programmatic approach to projects focused on achieving equitable health in urban areas.  

It includes the creation of our three fundraising Charities: Guy’s & St Thomas’ Charity, Evelina London Children’s Charity and Guy’s Cancer Charity, which all support patient care and staff welfare at Guy’s and St Thomas’ NHS Foundation Trust.  

The approach to managing our endowment has also undergone a transformation. It’s now managed on a dual mandate of health impact and financial returns, with a recent announcement to increase our impact investing allocation to £100m, the largest impact investment allocation made by a UK charitable foundation. 

We’ve seen the successful completion of the first five years of our 30-year strategy, and now set up for the next five. The Foundation is also firmly focused on embedding the principles of diversity, equity and inclusion in everything we do – which is fundamental to achieving our mission.
