What is MAMCCO?

MAMCCO is an ecumenical choir and orchestra passionate about sharing the gospel through sacred music, including Handel's Messiah.  Founded in 2009 as the result of a grassroots effort, MAMCCO began with a single presentation by a 70-member chorus, 16-piece orchestra, and 5 soloists.  We have continued to grow and have offered two presentations in most years. We strive to also offer a spring presentation. This year, we are celebrating our 15th anniversary!

MAMCCO is a 501(c)(3) charitable organization in the state of Wisconsin. Donations to support our ongoing mission are tax-deductible.
