Our Team
Bronwen Greenfield
Bronwen is the Founder and Managing Dietitian behind Trusted Dietitians, bringing expertise and passion to every aspect of the business.
Since becoming a Dietitian in 2017, Bronwen has been committed to providing evidence-based, compassionate, and practical nutrition advice that fits real-life needs. Her approach focuses on a step-by-step, anti-diet philosophy, helping clients heal their relationship with food and develop a sustainable, positive mindset around nutrition.
While Bronwen's passion for nutrition education first began through her personal brand, Diet Free Dietitian, her focus is now firmly on the continued growth and development of Trusted Dietitians. She works closely with corporate organisations, wellbeing providers and referral partners to make nutrition support simple, accessible and impactful. Bronwen understands that many organisations recognise the importance of nutrition but often lack the time, resources or expertise to build and manage a nutrition offering themselves. Through Trusted Dietitians, she has created a ready-to-go solution, allowing organisations to confidently offer professional nutrition support while her team manages the setup, delivery and ongoing service.
As an experienced nutrition educator and media Dietitian, Bronwen has shared evidence-based nutrition advice through Channel 7 Sunrise, Women's Day, The Daily Telegraph and other media outlets. She is particularly passionate about modernising nutrition education through engaging workplace presentations, webinars, online learning modules, digital resources and wellbeing programs that make nutrition information practical, accessible and relevant.
Bronwen also takes pride in supporting and mentoring the Dietitians within the team, ensuring they feel empowered to deliver exceptional care. She carefully onboards talented, compassionate Dietitians who align with the values of Trusted Dietitians, building a team that individuals and organisations can rely on.
