After 20 years of operating as a junior high school, a grassroots group of parents had a dream to provide a Christian Adventist day academy for Seattle and the surrounding areas. After two years of gathering information, compiling data, creating reports, endless prayer, and countless meetings with the board members from 25 churches and the Day Academy Committee, their dream became reality—the Washington Conference Board of Education voted 17-1, approving the formation of a new day academy.
In 1997, Puget Sound Adventist Academy was officially born, with 9th-11th grades. In May of 1998, the school graduated its first class of 12th graders. During the 1999-2000 school year, PSAA underwent a full self-study accreditation and received the maximum four-year term of accreditation.
Since its early beginnings, PSAA has continued to grow and better its program and is well known for the community that surrounds it.
