Joe explains his reasons for supporting the BTF: I was born with congenital hypothyroidism and two years ago began volunteering with the BTF. I have seen first-hand the fantastic support they provide to people living with thyroid disease, from babies to older people. Joe and Ian’s efforts raised £247 for the BTF.
