The Longmont Symphony Orchestra’s mission is to foster and promote the appreciation and understanding of symphonic music through performances and educational programs.


The Longmont Symphony Orchestra (LSO) was founded in 1966 by adult education director Phil Mattoon, and conductors, Leo Meyer and Walter Birkedahl. The first concert was held in April 1966. In 1970, Leo Meyer became the conductor and served in that position for twelve seasons. After his retirement in 1983, our present conductor, Dr. Robert Olson, was selected as Music Director of the LSO. After 33 years, Dr. Olson has announced his retirement. He will open and close our 50th Anniversary season in 2016-2017 by conducting our October 2016 and May 2017 concerts.

During its first full season (1966-1967), the symphony presented four concerts with a budget of $1,645.00. Currently, in our 50th season, the LSO presents twelve performances per year (a six concert subscription series, two performances of the 5th Grade Concert, two performances of the Nutcracker Ballet, a Candlelight Concert and a July 4th concert) and has an active educational outreach program, with an annual budget of approximately $225,000.00.
