The Kettle Moraine Symphony was founded in 1968 as the Moraine Symphony Orchestra by its current Music Director, Albert (Bud) Asch and a group of music enthusiasts, and was sponsored by University of Wisconsin - Washington County in West Bend.

KMS currently boasts a roster of about 60 semi-professional playing personnel and a dedicated Board of Directors. The orchestra's home stage is in the beautiful Schauer Arts and Activities Center in Hartford, Wisconsin. Other performance venues include Holy Angels Church and Our Saviour's Lutheran Church in West Bend, with Kewaskum Elementary school hosting the children's concert this year.
