Our Team

In order to keep its overheads to a minimum, the CGD Society does not employ any staff directly. Instead it collaborates with Genetic Disorders UK to ensure that the charity is run professionally and at a low cost base.

Claire Jeffries, Charity Coordinator

Claire has personal family experience of CGD and so has a good understanding of what life is like living with the condition. As Charity Coordinator Claire oversees the day-to-day management of the charity and is the main point of contact for our members.

Claire also raises awareness of the charity and the services and support it provides and promotes fundraising events and activities to CGD Society members.
