Give To MCO

Our purpose is to teach and encourage excellence in quality sacred and classical music. Founded in 2007 in Orange County, California, by brothers Brett and Brandon Stewart, MCO now has over 5,000 participants in seven on-site locales: California (Orange County), Arizona (East Valley), Texas–Austin, Texas–Dallas, Utah (Utah Valley), Idaho (Boise), and Kansas City (KS and MO). Each MCO locale houses four non-auditioned choirs for children and youth, as well as an adult choir and symphony orchestra, both comprising accomplished volunteer singers and instrumentalists.

The organization is made up of hundreds of volunteers who represent a variety of faiths and understand that this cause is larger than themselves.
