Ark announces new CEOs: Katie Oliver and Patrick Wall

The Boards of Ark and Ark Schools have appointed two new CEOs to succeed Lucy Heller, who steps down at the end of August after a remarkable 22 years at the helm.

Katie Oliver will lead Ark, the education charity, and Patrick Wall will be CEO of Ark Schools, the multi-academy trust. 

Katie Oliver is Ark’s current Director of Ventures and Managing Director of Ark Start. Katie has been part of Ark for 20 years, holding various leadership roles including Operations Director, responsible for growing the schools network and central services. Most recently she established Ark Start – Ark’s growing group of successful nurseries – which sets out a new model for early years education. As CEO she will continue to oversee Ark Start, as well as Ark’s national curriculum and teacher training partnerships, the charity’s sector-wide work through EdCity, and innovation projects focused on addressing some of the most pressing issues facing education.

Patrick Wall is the co-founder of the Centre for Education Systems (CES), an international organisation supporting education policy making. CES has worked closely with the Department for Education on a variety of issues, most recently on SEND. Patrick is a former Sutton Trust Fellow and he also established Target Schools, the University of Oxford’s first access programme in 1982. He has had a long association with Ark, serving as Chair of Governors at Ark Academy for fourteen years. Patrick will combine his education experience with strong financial, operational and technical knowledge – gained through a successful career as founder and CEO of a large, international software company.

Both CEOs will commence their new roles in September 2026. They will report to their respective Boards and work closely together to advance Ark’s mission – ensuring every child, regardless of their background, has access to a great education and real choices in life.

Tina Alexandrou, Chair of the Board for Ark Schools: “Patrick Wall is a longstanding champion of Ark Schools, and we are delighted that he will now take up the reins at the trust. Patrick has a deep understanding and knowledge of education, a passion for the mission, and a track record for leading organisations through growth, innovation, and operational transformation – all of which will be invaluable as Ark Schools seeks to increase its impact over the coming years.”

Ian Wace, Chair of the Board for Ark: “The appointment of two CEOs reflects the scale and ambition of both the charity and the MAT. Katie Oliver is an established leader with deep organisational knowledge, a passion for equitable education, and a relentless drive for meaningful system change. We are confident that, working together, Katie and Patrick will build on Lucy’s incredible legacy.”
