The International Order of the Rainbow for Girls is a non-profit service organization for girls between the ages of 11 and 20. Rev. W. Mark Sexson founded our order in April of 1922. Rev. W Mark Sexson sought to develop an organization where young women could build self-confidence and leadership skills, all while serving their community. The organization promotes community service, as well as love and service to their schools, their homes and to each other.
