About

Annabel Griffiths joined Costello Medical in 2015 and quickly became a phenomenal force. She established then led our rare diseases division from 2018, then guided rare disease teams worldwide and mentored countless colleagues. Her work strengthened our partnerships in the field and left a lasting, positive impact on the rare disease community.

In early 2024, Annabel was diagnosed with a rare cancer. She faced her illness with the same courage she brought to her work, receiving treatment at Addenbrooke's Hospital and compassionate care at Arthur Rank Hospice, in Cambridge UK. She passed away on 01 March 2025.

Annabel changed the direction of Costello Medical for the better - forever. Words can't fully capture the person she was - someone who approached life with positivity, humour, ambition, compassion and selflessness.

March 2026 marks one year since Annabel's passing. A team of 16 Costello Medical runners, with many more colleagues and supporters on the sidelines, will take on the Cambridge Half Marathon on the 8 March to honour Annabel's memory and support Arthur Rank Hospice.
