Founder, CEO and Board Member
Sarah has two daughters, one of which (Bella), lives with eosinophilic oesophagitis (EoE) and was the catalyst for her forming the non-profit organisation in November 2009. Working in a volunteer capacity for 12 years, until 2022, Sarah was the President until being appointed as part time CEO from 2022. Her goal is to make sure that anyone who lives with an eosinophilic gastrointestinal disease can turn to ausEE for support and to help raise awareness for eosinophilic gastrointestinal diseases in Australia. For every new member that joins ausEE, Sarah's passion and commitment to the organisation strengthens. She strives to improve the quality of life for all people living with eosinophilic diseases.
In January 2023, Sarah was awarded the Medal of the Order of Australia (OAM), for her service to community health. Sarah is a member of the Institute of Community Directors Australia.

Charity Ambassador
Eddie Woo
2018 Australia's Local Hero, mathematics teacher for the NSW Department of Education and TV Host of Teenage Boss, Eddie Woo has become an Australian household name and we are delighted to have him as our Charity Ambassador.
Eddie Woo has been inspiring students across the globe through his YouTube channel, Wootube for nearly 10 years. In 2018, Eddie joined ausEE Inc., as our Charity Ambassador to help raise awareness for eosinophilic gastrointestinal diseases (EGID), a cause close to his heart.
Eddie is a proud father with three children who all live with some form of allergic disease. This includes asthma, eczema and multiple immediate food allergies. One of them has an EGID, namely, eosinophilic oesophagitis (EoE). EoE is a rare allergic disease caused by eosinophils, a type of white blood cell, being found in above-normal amounts in the oesophagus which can cause inflammation and tissue damage. This has caused Eddie’s child to live with symptoms such as difficulty swallowing, vomiting, stomach pain and ‘failure to thrive’.

“The difficulties are every day. Eating itself has become a really difficult experience, because eating was associated with an incredible amount of discomfort and pain just to squeeze food and drink down. In addition, there is a social aspect to food that is very difficult for others to understand. Since relationships are often formed through mealtimes, our children have had to struggle with having a complex and cautious relationship to even the simplest social gatherings.”
Eddie Woo, 2018
Eddie has been teaching for 16 years and in 2012 when a student of his had Pancreatic cancer, he felt the urge to help as much as possible and started to record all of his lessons and post them on YouTube. It was astounding to see the amount of views, and his Wootube channel now has more than 1.7 million subscribers and nearly 157 million views. These videos are helping people around the world not only understand maths but find joy in maths. For our ausEE members who have high schoolers, this extra assistance with maths has been invaluable for their students as many have experienced the impact living with a chronic illness can have on school work. On Mathspace you can find Eddie Woo’s maths videos mapped to the Australian and state-specific curricula.
Eddie Woo reads Meet Arabella
In this video you can watch Eddie Woo reading our book Meet Arabella. Made in support of National EOS Awareness Week 2021, it’s a special video to watch with your kids, friends and family to help explain eosinophilic oesophagitis to them. Your child might even like to share the video with their teacher and classmates.
