Professor Trevor Purt, the Chief Executive of Hywel Dda University Health Board, is to leave his post.
He will take up the role of Chief Executive of Betsi Cadwaladr University Health Board in June.
During his time in west Wales, Mr Purt has overseen significant new developments including the new Urgent Care Centre and Renal Unit at Withybush Hospital.
But he is likely to be best remembered for the hugely controversial ongoing service changes which threaten the Special Care baby Unit at Withybush Hospital as well as maternity services, and has prompted several large demonstrations from angry campaigners.
Mr Purt joined Hywel Dda University Health Board in September 2009. He said: “I am sad to leave as I have thoroughly enjoyed my time in the University Health Board but feel the time is right for new challenges in North Wales. “We have come a long way in the last 4½ years and there is still more to do to ensure that Hywel Dda has the right services in the right place to provide the very best healthcare.
“I have full faith in my executive directors, the wider management and clinical teams and Karen Howell who will be interim chief executive officer to move forward to ensure our services continue to develop.
“These have not been the easiest of times and I want to personally thank all staff for their dedication and commitment – you are the university health board’s greatest asset.”
Chris Martin, Chair of the University Health Board, who is also to leave the organisation this year, said: “Trevor was the first chief executive officer of the new integrated health board and has successfully lead the organisation through some difficult times. During his time we have seen a significant improvement in quality and performance due in no small measure to his leadership. We are sorry to see him leave but wish him well in his new role.”
