The St. Charles County Family YMCA began in 1966 as an extension of the Northwest County Family YMCA branch. Programs such as day camp, Indian Guides, volleyball and swim classes were held at St. John’s Church.
Branch status was granted in 1973, and eight years later, the current 42,000 square-foot facility was constructed. It included a gymnasium, swimming pool, running track, gymnastics center, locker rooms and meeting rooms. The branch opened a child care center in 1980, providing families in St. Charles County with an affordable child care alternative.
An extension of the branch was created in 1984 to serve Lincoln, Warren and western St. Charles counties. In 1999 the extension, located in Wentzville, MO, received branch status and was named the Tri-County Family YMCA.
