Sally studied to be a dietitian after her diagnosis of coeliac disease (almost 20 years ago). At the time that many dietitians couldn’t provide the support she needed as a type 1 diabetic with coeliac disease.

After graduating with a science degree, a Bachelor of Nutrition and Dietetics, Sally set up in private practice with a special interest in coeliac disease. She was shocked to find that it took many people up to ten years to get a coeliac disease diagnosis and that about 80% of people with coeliac disease go undiagnosed.

Most recently Sally has been studying coeliac disease and the role of the gluten-free diet in fertility and pregnancy. Sally is a scientific advisory board member and member of the Early Life Nutrition Alliance,and she is recognised as a leader in Early Life Nutrition. Sally speaks Internationally, training other dietitians on clinical issues related to fertility, pregnancy and postpartum. Sally also studies and works with couples with thyroid conditions, PCOS, all types of diabetes, on minimising risk of gestational diabetes, endometriosis and gastrointestinal issues including IBD, coeliac disease and bariatric surgery. She still has a special interest in all cases of T1DM, coeliac disease and other women’s health issues due to her own personal experience.
