Mariann Koop-McMahon

Raised in a family of artists, Mariann’s lifelong love of stories, myth, legends, folktales, and fairytales found an outlet at Art Camp in 1998 as a parent. Soon after, she became part of the administrative team that grew Art Camp to 1200 campers spanning seven weeks. Holding a B.A. in Communications and History from the University of Portland, Mariann’s career has been predominately supporting non-profits through grant writing, fundraising, public relations, communications, and graphic design. Other experiences include those of Junior Great Books Leader at Oregon Episcopal School, and as an award-winning watercolor painter exhibiting with Watercolor Society of Oregon and Oregon Society of Artists.  Passionate about social justice and art, Mariann can be found weekly at her quilting group, making quilts for women and families in local domestic violence shelters. A third generation Oregon native, Mariann and her family reside in a house in the urban woods alongside neighboring owls.
