Dr Sushil Jathanna, 52, replaces GP Dr Paul Zollinger-Read, interim chief executive at NHS Great Yarmouth and Waveney, since the departure of Mike Stonard in May.
He began his medical career as a senior house officer before becoming a registrar in medicine for the elderly at West Norwich Hospital. He then specialised in public health medicine and went on to become the director of public health in Colchester and Tendring PCTs.
After working in the private sector for six years, leading Care UK's healthcare division as managing director, Dr Jathanna was keen to rejoin the NHS because of his passion to serve the community.
Dr Jathanna is currently working as interim director of World Class Commissioning Transformation for NHS North East Essex.
He said: ‘The strong public service ethos of the NHS is something I admire. I want to bring my NHS background, which included the role of director of public health, as well as my private sector expertise into the trust at what is an interesting and challenging time across the NHS.'
