Angie Franklin began her career in medical education with a clear purpose: to help communicate the remarkable advances being made in science, technology, and medicine. As the founder of Chameleon Communications International, a science and medical education company, she built an organisation rooted in the power of change.

Under Angie’s leadership, Chameleon focused on communicating medical innovations in the fields of cardiology, cancer, ophthalmology, and many other indications. The company’s work was driven by the belief that facilitating innovation—through clear, impactful communication—can play a vital role in transforming how medicine is practiced. This mission was recognised at the highest level when Chameleon received the Queen’s Award for Enterprise in Innovation and International Trade.

Today, Angie is turning her attention to one of healthcare’s most misunderstood and stigmatised challenges: weight and obesity. She is committed to replacing the negative, destructive narratives with evidence-based, compassionate solutions. Her goal is to inspire transformative change—for the body, mind, and spirit.
