The Montessori School of McLean is located behind the Chesterbrook United Methodist Church in the Chesterbrook area of McLean. The School is in a modern building that its leaders call "the children's house." It was founded in the early 1970s, just as McLean was transforming from farmland to suburban subdivisions. Its young graduates tend to continue in private schools. During the 2012-2013 school year, the school will celebrate its 40 th anniversary.
