Aidan
began its life as St. Aidan School on the campus of Dumbarton
School for Girls, a Catholic college for women on what is now
the UDC - Van Ness campus. It was founded in 1961 by Catholic
parents who wanted a Montessori school for their children. They
incorporated as the first Montessori school in Washington as
a 501-c(3) not-for-profit corporation and formed the first Board
of Directors. Soon after, St. Aidan moved to Military Road where
it leased space for 33 years from Temple Sinai. It changed its
name in 1985 to Aidan Montessori School to reflect its secular
nature.
Aidan purchased the St. Thomas Apostle Church School in 1996
and moved to its present location in historic Woodley Park.
Over the years it joined with other independent schools in the
greater Washington area and embraced the practices which guide
independent schools nationwide.
