In early November 2026, Karl was diagnosed with an incurable, high-grade brain tumour.

Karl is a husband to Katie, a dad to two boys - Zachary and Oscar, and Head of Chemistry at The King's School in Grantham, who is loved by his school community. He’s the kind of person who shows up for others. When his friend Andy was facing his own brain tumour diagnosis, Karl cycled 100 miles to help raise money for his treatment.

Now it’s our turn to show up for Karl.

Karl recently had brain surgery, and surgeons removed around 90% of the tumour. The surgery went as well as it could have, but the family have been told his condition is life-limiting and there is currently no cure. Karl and Katie are working with his neuro-oncology team on a treatment plan, and they’re determined to explore every possible option, including clinical trials and overseas aid.

They’re also determined to balance treatment with quality of life, and to make the most of every moment together as a family.
