Michael Fanning joined Croydon Health Services NHS Trust as its new interim director of nursing on 9 December.
Mr Fanning has a background in managing an accident and emergency department, and will join Croydon as it prepares to care for many more people during the busy Christmas and winter period.
Since August 2014, he has been interim deputy chief nurse at Milton Keynes Hospital NHS Foundation Trust, where he has overseen improved performance in infection control.
He has also held a number of senior positions at hospitals around the country, as well as spending 18 months at the Department of Health.
In 2009, he jointly led a project for South Central England strategic health authority, looking specifically at nursing and midwifery care.
The recruitment process for a substantive director of nursing began on the 5 December. Interviews are expected to take place in February next year.
Mr Fanning’s appointment came as the trust announced the arrival of 38 nurses from Italy, as it struggles to fill vacant posts like many trusts across the country.
