About Action for Pulmonary Fibrosis Action for Pulmonary Fibrosis (APF) is the UK’s leading patient charity dedicated to improving the lives of individuals and families affected by pulmonary fibrosis. Our mission is underpinned by values of compassionate, bold, expert and collaborative. We believe in creating a supportive environment in which both our employees and beneficiaries can thrive. Founded in 2013 by people affected by PF and clinicians, APF has grown into a respected national charity rooted in community and evidence. We provide trusted information and support, help a growing network of support groups, campaign to improve access to care and invest in research to bring hope of new treatments. APF strives to be an organisation of equity and inclusion, welcoming people from all backgrounds – our team and volunteers aim to reflect the diverse communities we serve. We have just launched an ambitious five-year strategy (2025–2030), co-created with the PF community, which focuses on expanding support, transforming care, and accelerating research. This strategy marks a step change with a clearer focus, stronger delivery model and greater ambition to ensure no one faces pulmonary fibrosis alone.
