Jillian O'Grady, Family Ambassador

Jillian is mum to three gorgeous, bubbly and fun children. Rory 9, Anna 6 and Juliet 18mths old. 

Sadly, in 2019, both Rory and Anna were diagnosed with Sanfilippo Type A (attenuated), marking the beginning of a very different life journey than the one she and her husband had imagined. 

Since then, Jillian has navigated the uncertainty of this condition and its potential treatment opportunities. Her lived experience, knowledge and understanding of the research, and passion to find a cure not only for Anna and Rory but for all children with Sanfilippo, makes her an inspiring Family Ambassador. 

The purpose of this voluntary role is to be the representative of the collective family voice when needed and to be a reassuring point of contact for families wanting to connect with others who "just get it".
