Management team

Profile photo of Paolo Pieri
Our CEO Paolo Pieri is leading Circle Health Group towards an exciting future that puts people first - whether that be our patients or our employees. Since becoming CEO in 2016, Paolo has been instrumental in growing the business at an unprecedented rate, spearheading developments in technology, investment, social purpose and strategic vision. He recently led the buyout of the largest private hospital operator in the UK, BMI Healthcare, including a £1.5 billion transaction that delivered the sale and leaseback of 30 hospitals.

Paolo has constantly challenged the group to achieve best-in-class when it comes to technology and digital innovation. As a result, Circle Health Group is the fastest-growing hospital operator in the UK digitally. Paolo has reimagined the company, transforming it from a minor player with minimal operations to the largest in the industry.

Most importantly, Paolo has the wellbeing of people firmly in his laser-like focus. Despite the challenges of integrating two diverse and complex hospital groups during the pandemic, Circle Health Group was recently voted one of the Top 25 Big Companies to work for in the Sunday Times' annual awards for 2020/21, based on substantial employee feedback on the group under Paolo's leadership.
