A Brief History

The Beginning

InFirst Seventh Grade 1978, led by founding headmaster the Rev. Warren “Jess” Borg, St. Andrew's opened in the basement of Pilgrim Lutheran Church on Massachusetts Avenue with 40 students in grades 7-9, nine part-time teachers, and a school library comfortably housed on four shelves. From its early days, the school cultivated challenging programs in a joyful and supportive atmosphere, celebrating its students’ diversity of interests, backgrounds and abilities and developing each child’s potential in the “four pillars” of academics, arts, athletics, and spiritual life.

The school grew quickly in reputation, programs, and enrollment, outgrowing two locations before moving to the former North Bethesda Junior High School campus on Bradmoor Lane in Bethesda in September 1981. With 245 students, 28 teachers, and its first graduating class that year, St. Andrew’s had entered the ranks of full-fledged independent college-preparatory schools.


Rapid Growth

In 1989 Montgomery County decided to reclaim the Bradmoor site, and St. Andrew’s began a search for a new home. Led by the energy and resourcefulness of its Board of Trustees, St. Andrew’s purchased a 19.2-acre site on Postoak Road in Potomac, Maryland in Ribbon-cutting for new building, 1998.1993. At one critical juncture, six trustees personally guaranteed the loan that secured the Postoak Campus and the school’s future.

In 1998, St. Andrew's dedicated the Postoak Campus and quickly grew to 450 students in grades six through twelve. From 2008 to 2010, St. Andrew’s expanded again, adding grades preschool through five and a new Lower School campus by acquiring the former St. Francis Episcopal Day School on River Road in Potomac Village.



To the Present Day

St. Andrew’s strategic vision is to be the destination school for research-informed teaching, learning, and service. In 2011 St. Andrew’s launched its Center for Transformative Teaching & Learning (CTTL), which oversees educational research, partnerships, and professional growth at St. Andrew’s and trains public and private school teachers and administrators throughout the mid-Atlantic region, including the Washington, D.C.-area Teach for America faculty.

Lower School studentsIn September 2016, St. Andrew’s opened a new 43,000-square-foot Student Center on the Postoak Campus. This transformative building includes two gymnasiums, a bright and spacious student commons, a beautiful fitness center and dance studio, and expanded research and workshop space for the CTTL. The Student Center project has also created a new central, grassy quadrangle for our close-knit community. In the fall of 2019 the school opened a new 31,000-square-foot preschool to grade 5 Lower School building, with signature spaces for science, design, and the arts. This exciting project caps a decade of strategic expansion and brings our full community together on the Postoak Campus. St. Andrew’s is now the largest school in the Episcopal Diocese of Washington, having grown to 640 students in preschool through grade 12.
