Sarah Chamberlin is the founder and Executive Director of flok Health, formerly National PKU News. flok supports people with inherited disorders of protein metabolism through community connection, education and resources, and community-led research. Inspired by her daughter’s PKU diagnosis, Sarah created How Much Phe in 2013. More recently, she guided the organization’s transformation into flok, including the development of the flok app—a tool that helps individuals, caregivers, and clinicians understand diet, mood, symptoms, and activity, and contribute to a research dataset grounded in daily care.
