Davina is approaching 70 years young and going stronger than ever. Two years ago as part of her weight-loss programme, she donated a kidney to her son, David, who had been on dialysis for some time.

Both patients continue to do very well and they'd just like a little of your help to show appreciation to the amazing team at St Hellier hospital in London, who carried out this modern miracle.

Donating through Justgiving is quick, easy and totally secure. It’s also the most efficient way to sponsor me: South West Thames Kidney Fund gets your money faster and, if you’re a UK taxpayer, Justgiving makes sure 25% in Gift Aid, plus a 3% supplement, are added to your donation.
