The Littleton Symphony Orchestra (LSO) began as a twelve-member string ensemble in the fall of 1984. The next year, the group added wind, brass, and string players, performing as the Littleton Chamber Orchestra. In 1990, the group grew to a full-size symphony and changed its name to the Littleton Symphony Orchestra. The LSO performs repertoire normally associated with professional orchestras and has developed a reputation as one of Colorado's most respected and versatile community orchestras. The LSO is dedicated to the growth and quality of its musicians and to the cultural life of the south suburban area. It has collaborated with many other arts organizations and frequently features soloists who are prominent regional musicians as well as national emerging artists.
