Paul May – Non-Executive Director

Paul is a councillor with Bath & North East Somerset Council serving Publow and Whitchurch ward. He sits on the Health and Wellbeing Select Committee and the West of England Joint Scrutiny Committee.

Paul joined Sirona in August 2015 as he believed the opportunity for front line staff to work together for the benefit of our community was so crucial to more joined up care that he wanted to be part of making that happen.

He has around 50 years of public sector experience including non-executive directorships with health organisations and believes the staff are our most valuable asset.
