Bianca Bryson

Chief Marketing & Partnerships Officer

Bianca has worked within the marketing profession for over 12 years with the majority of that time spent within the FMCG industry for global brands. She enjoyed doing this in both Australia and the United States of America – working for brands such as Walt Disney, Nestle and l’Oreal. However, in recent years she decided to take that experience and made a move into the ‘not for profit’ industry, with a specific interest in anti-human trafficking.
