1960's
By 1966, enrollment totaled 215 students. In order to house the growing student body (upper school, pre-school and primary school), an additional wing was built in 1968.
1970's
Enrollment continued to grow during the 1970‘s. Further additions to the school were made in 1972 and 1974. An important feature of the construction in 1974 was a library. In June 1977, Mrs. Dorothy Startt retired after 43 years of dedicated service. Enrollment was at 355 students. In 1978, the pre-school program was discontinued. A transitional period occurred between 1977 to 1979 during which Mr. Thomas M. Green was appointed Headmaster, followed on an interim basis by Mr. Edward C. McEachron. Mr. Russell A. Anderson became Headmaster in July 1979.
1990's
Enrollment was once again on the rise. In 1990, Mr. Ferrer left to take another post and Mr. Neil Mufson became headmaster in July, having previously served as Upper School Head of the Ensworth School in Nashville, Tennessee. An after-school care program was created and the first Grandparents’ Day held. In 1994, the school celebrated its 60th Anniversary and began an ambitious fund raising campaign to build a new library, renovate and expand facilities, and increase endowment. Throughout the 1990’s, student enrollment consistently increased. In 1999, The Country School Values program began.
