Sir Ian Botham has backed the appeal for the diabetes centre since 2003
A centre in Surrey offering specialist diabetes care, which has taken nearly two years to construct, is to be officially opened by Sir Ian Botham.
The Stephanie Marks Diabetes Resource Centre at St Peter's Hospital, in Chertsey, has been built in memory of a local teenager who died in 2002.
Stephanie died from complications from Type 1 diabetes at the age of 17.
The ex-cricketer, patron of the appeal which raised more than £1m for the centre, will open it on 20 May.
The building will offer out-patient treatment, education for patients and clinicians and medical research.
It will serve about 450,000 residents in Elmbridge, Hounslow, Runnymede, Spelthorne, Surrey Health and Woking.
Trust medical director Dr Mike Baxter said: "The community needed a specialist diabetes centre where diabetes treatment, education and research could all be delivered to the ever-growing numbers of people who need our expert help.
"Out of Stephanie's tragic death there has been incredible support for this project, and that will not only provide a lasting legacy in her name but will be a valuable asset for our patients of all ages, their relatives and carers."
