Saint Thomas School is an independent K-8 in Medina founded in 1951 as a parish school of St. Thomas Episcopal Church on the east shore of Lake Washington. The school transitioned to nonsectarian independent status over time and is NWAIS-accredited, serving roughly 250 students from Junior Kindergarten through 8th grade on a single Medina campus.
In Seattle-metro private K-8 coverage, Saint Thomas pairs with the legacy independents that anchor concentrated-wealth enclaves — Epiphany in Madrona, Bertschi on Capitol Hill, Villa Academy in Laurelhurst — rather than the gifted-only K-8s (Open Window, The Evergreen School) or the post-2000 secular-academic schools (Bellevue Children's Academy, Chestnut Hill Academy). It is one of the few Eastside K-8 indies with founding roots predating the Microsoft-era growth that produced most of the region's current private-school capacity, and its Medina address places it inside one of the smallest and wealthiest cities in the state.
Matriculation feeds the elite Seattle-metro 9-12 cohort, with the Lake Washington-corridor secular indies — Lakeside School, The Overlake School, Eastside Preparatory School, University Prep — the consistent landing spots for Medina-area families continuing in private school. The Bush School and The Bear Creek School appear as secondary destinations.
