Boulder Chamber Orchestra (BCO) is Boulder's premier chamber orchestra, playing to sold-out audiences for more than 12 years. Established in 2004, the Boulder Chamber Orchestra (BCO) aims to promote classical musical arts and education and is home to some of the area’s most talented musicians in the area.

The mission of the BCO is to promote classical music and arts, as well as education in classical music by presenting an array of live and recorded performances of the highest sound quality and standards. The BCO also aims to enhance the reputation of the surrounding Boulder community through world-class music and arts.

The Boulder Chamber Orchestra offers many ways in which people can get involved with the orchestra and classical music industry from playing in the orchestra and volunteering at concerts to making donations and contributions and marketing the orchestra’s programs by word of mouth. The orchestra also partners with several organizations to promote classical music and educate, build and strengthen the community, including the Emergency Family Assistance Association (EFAA) for a food drive and Boulder High School. The BCO offers the Eva Mesmer Instrument Scholarship each which involves learning how to play the viola and violin, which were left to the orchestra by Eva Mesmer.

The Boulder Chamber Orchestra is located at 4735 Walnut Street in Boulder and presents a calendar of performances throughout the year. The BCO performs at one of two venues in Boulder, namely the Boulder Seventh-Day Adventist Church on Mapleton Avenue and the Broomfield Auditorium on Community Park Road. Classical music lovers can purchase a season pass for the BCO’s performances and enjoy free concerts all year, as well as additional ticket vouchers for friends, quick access to all shows, exclusive invitations to BCO events and discounts at many restaurants and stores in Boulder.
