Her story, which was told on various platforms including ITV News, united the public in one common goal - to get her to the US to receive potentially life saving treatment and that they did!
Six-year-old Isabelle from Thornton Cleveleys who attends Anchorsholme Primary School was diagnosed last July as a High Risk Stage Four Neuroblastoma - a rare form of cancer that affects mostly babies and young children which carries with it a 50 percent survival rate.
Mother Louisa Moss and father Blaine Grundy alongside her big brother Grayson have been unrelenting in their fight to get her the treatment she so desperately needs.
Overwhelmed by the kindness of strangers, Isabelle's mother Louisa said: "On behalf of the Grundy family we would like to thank the community as a whole for their incredible support and generosity, without you all this wouldn’t of been possible, thank-you from the bottom of our hearts."
Louisa's good friend Emma Robinson who started the GoFundMe Page alongside Samantha Douglas and has relentlessly campaigned since, said: "Last night (Sunday) while at the Stand up for Isabelle event we went over the £200,000 mark.
"We have done this in five weeks and five days!
"Thank you to every single person who has helped us hit this amount. It's just incredible.
"The way our community has pulled together for Isabelle to raise money for this potentially life saving treatment is just amazing."
Emma's son Theo who is one of Isabelle's best friends and class mates also took on his mother's kind nature by ensuring his school friend was not left out at Christmas while she was in hospital and raised money to get her Christmas gifts.
Eric Taylor who goes to school with Isabelle's brother Grayson was adamant he wanted to do something to help and decided to run 200 miles in less than 50 days.
