Dr Samantha Hiew is a multi-award-winning keynote speaker, lived experience scientist, and founder of ADHD Girls - a social impact platform transforming how society sees and supports neurodivergent women and underrepresented communities. Diagnosed with ADHD and autism in her 40’s after years of feeling unseen, Sam created the space she longed for - where science meets lived experience, and personal truth becomes a catalyst for cultural change.

Sam has spoken to over 100,000 people, trained 100+ FTSE companies, and led the UK’s first large-scale event spotlighting the lives of AuDHD women and the diagnostic gaps they face. Named a Difference Maker by PBS America and Positive Role Model for Gender by the National Diversity Awards, Sam brings heart and academic rigour to every stage and page. Sam’s debut book, Tip of the ADHD Iceberg, is a compassionate guide for late diagnosed neurodivergents to navigate life after diagnosis and finding your voice. With a PhD in medical science and a background in communications, Sam translates research into real-world relevance—helping neurodivergent people feel seen, supported, and empowered.
