Our story
Sal and Cat grew up together in an all-sister household on a farm in regional Victoria. Family dinner time conversations often centred around curious discussions about the thoughts and feelings that influenced human behaviour. Soon enough, this foundation set the stage for two careers in clinical psychology.
In 2023, Cat was presenting her PhD research at the European Health Psychology Society conference in Germany while Sal was on a sabbatical hiking across Europe. They met in Berlin on a warm autumn evening, sitting on the terrace of a tucked-away bar, enjoying a glass of red wine and exchanging family stories. There was something in the air—a creative buzz among the locals and the pleasure of each other’s company.
Cat’s eyes sparkled. "Let’s create something together!" she exclaimed. "Something fun, innovative, and helpful. Maybe something that supports women and establishes new frontiers in digital health. We have the skills and experience. We just need to give it a go!"
Sal sat in silence for a moment. She had long dreamed of starting a business but had always been too nervous to do it alone. But creating something with her sister? That would be fun. A smile slowly spread across her face.
In unison, they raised their glasses.
“Let’s do it!”
Twelve months later, SisterTalk was born.

SENIOR CLINICAL PSYCHOLOGIST, GROUP FACILITATOR
Sally Brown
Sal is a clinical psychologist with over eight years of experience in the field, including senior leadership roles within healthcare teams. She began her career in digital mental health at Headspace's national office, which ignited her passion for ensuring that all Australians, regardless of where they lived, could access high-quality mental health care.
Sal has continued to expand her expertise in digital mental health, working across telehealth addiction treatment, online social prescribing, digital education, and virtual wellbeing workshops. In 2022, she expanded her knowledge by travelling to North America to learn from global leaders in digital health at the ISRII conference. After North America, Sal took an 'adult gap year’, embarking on a journey that saw her walking across Spain, building a yoga studio in Georgia, and teaching English in Morocco.
Sal is now based in Naarm/Melbourne and currently works at the Food and Mood Centre at Deakin University. Here, she delivers group therapy for people with depression and bi-polar and is investigating the impact of healthy eating and exercise on depression.
