GOSH’s mission to beat serious childhood illnesses

Support for families and children
With your help, we provide services to ease the burden on families, raise spirits and support young people through life-saving treatment.

We provide the high-tech hardware to ensure children at GOSH have access to the least invasive and most efficient treatments available.
