Lauren Keiser Music Publishing celebrated its tenth anniversary on October 31, 2018. With offices in St. Louis, San Antonio, and the metro New York area, the company has grown considerably following the acquisition of the Southern Music Company of San Antonio, TX in June, 2012.

Veteran music publisher, Lauren Keiser, started Lauren Keiser Music Publishing (ASCAP) and Keiser Classical (BMI) from the purchase of MMB Music's assets of St. Louis and is joining it with new deals and editions he is creating and developing. His almost forty years of being involved with Alfred, Cherry Lane and Carl Fischer Music publishing companies has provided a basis and foundation for a new music publishing company based on his experience. The firm publishes performance and music copyrights of gifted concert and symphonic composers in addition to producing publications of talented writers and artists.
