And if you've been to hospital in the city, you will know what an inspirational cause it is.
Its volunteers run shops which have raised hundreds of thousands of pounds for the health services.
Some of its workers have been giving outstanding support for years and we salute them.
Here's just a small Echo selection of those outstanding memories of the service in action.
