Saint Dunstans Episcopal Church has served the McLean community since 1956. The church first met at Chesterbrook Elementary School before moving to its own building on Kirby Road. Now, the church is housed in a strikingly modern building. The church maintains a Peace Garden where there is a sign in four languages that says, "May peace prevail on Earth." The church supports Martha's Table and Habitat for Humanity. Saint Dunstan was an Anglo-Saxon archbishop in the 10th Century.
