Boyer Children's Clinic
Boyer Children’s Clinic is a non-profit neurodevelopmental center and special education facility that has served children and families in the Puget Sound area since 1942. Founded by a group of doctors, parents, and volunteers to provide services for children with cerebral palsy, it has evolved into one of the region’s premier resources for children with neuromuscular disorders and developmental delays. Operating from two Seattle locations—the flagship clinic in Montlake and a satellite site in Magnuson Park—Boyer provides a comprehensive, interdisciplinary approach to early intervention and childhood development. The clinic is the largest provider of Early Support for Infants and Toddlers (ESIT) services in Seattle, primarily serving children from birth to age three. The highly-skilled staff includes therapists, nurses, educators, a developmental pediatrician, social workers, and family resources coordinators. Together, they offer physical, occupational, and speech-language therapies, as well as nurse coordination and medical consultation to ensure each child reaches their maximum potential and improves their quality of life. Boyer’s educational offerings include the Seattle Developmental Bridge Program, a specialized track for children birth to 48 months who may have missed early support windows or require help transitioning between programs. The clinic also features unique programs like CHERISH™, which supports children in the foster care system, and CONNECT, designed to eliminate barriers for families facing homelessness. All instructional and therapeutic models focus on functional daily living skills, social-emotional development, and empowering parents to be their child’s best advocate. Admissions are coordinated through a centralized intake department, with services funded through a mix of state-supported programs like ESIT, Medicaid, and private insurance. Boyer remains committed to accessibility, offering transportation support for eligible families and maintaining a strong partnership with community foundations. By fostering a collaborative environment between medical professionals and families, Boyer Children’s Clinic continues its 80-year legacy of providing hope and specialized care for children with complex developmental needs.
