The YMCA of Southern Indiana is charitable non-profit community service organization and is governed by a volunteer Board of Directors. It is run locally, but is affiliated with the YMCA of the USA. The YMCA of the USA provides consultation services, and represents the local Y’s on national issues. Locally the YMCA is a member agency of the Metro United Way.

The YMCA of Southern Indiana was established in 1969 as a branch of the YMCA of Greater Louisville. The YMCA operated for six years using local churches and schools for program activities. It was called the Clark County Family YMCA.

The current building at 4812 Hamburg Pike was dedicated in 1976. The YMCA then changed its name to the Graves Center YMCA. It was named after Clifford and Wilma Graves who donated the property for the building.

In 1986 the YMCA separated from the YMCA of Greater Louisville and formed an independent YMCA. To reflect the regional impact of the YMCA and its service to Clark and Floyd Counties, the agency incorporated as the YMCA of Southern Indiana.

Over the years, the YMCA of Southern Indiana acquired Camp Honor Bright, a former Girl Scout Camp, in Sellersburg and expanded the original facility twice. In 1996 a $1 million expansion added a fitness/wellness center, a Kids Adventure Room and Group Exercise Classroom. A second expansion of $4.8 million, completed in 2005, added another 30,000 square feet. The highlight of this expansion was the addition of three indoor pools: a family fun pool, a lap/instructional pool, and a warm water therapy pool.

Today the YMCA of Southern Indiana serves 9,800 members and 18,000 program participants.
