Speech–language pathologists (SLPs) may design and implement public health approaches that advance children’s language development. Universal, public health-informed SLP programmes could improve equity and access to SLP services for all children, including those from families that are historically underserved (e.g., socially and economically disadvantaged families). Social determinants of health, like food or housing insecurity, exposure to violence, or systemic inequalities (e.g., racism), may affect language development and also limit access to speech–language pathology services. This clinical focus article describes how a public health lens, trauma- and violence-informed care principles, and evidence about parent coaching in early language interventions were applied to develop a new programme titled Community Opportunities For Family Engagement and Empowerment, and Play and Learning Accessible for Youth (COFFEE and PLAY). The programme builds relationships between families and SLPs to (a) reduce barriers to service, (b) build parents’ capacity to support children’s language, and (c) promote school readiness.
