About us Parent Involvement Forum Stewart Leaver Stewart first contacted Solving Kids' Cancer in Nov 2017 shortly after this daughter Jossie, who was 4 years old at the time, was diagnosed with high-risk neuroblastoma. The family were treated at Great Ormond Street Hospital, and following multiple relapses, travelled to both Barcelona and Germany to access clinical trials not available in the UK. Sadly, Jossie passed away in Nov 2019. Since Jossie’s death, Stewart has continued to take an active interest in Solving Kids' Cancer and wants to use his experiences to help inform the charity’s approach to supporting parents and families. Stewart lives in Hertfordshire with his wife Cassie, and Jossie’s younger brother Dougie.
