Oregon Rainbow is organized into 19 community based chapters called Assemblies who are sponsored by Masonic Orders. Usually the sponsoring body is either a local Masonic Lodge, Order of the Eastern Star Chapter or Order of the Amaranth Court.
Oregon Rainbow Assemblies have regular meetings twice a month on a set schedule, as well as service projects and fun activities. The youth leader is called the “Worthy Advisor” who presides over the meetings where the girls attend to business and the workings of the Assembly; and perform memorized work. The girls themselves who range in age from 11 to 20 years old, with the guidance of their Mother Advisor and Advisory Board, are responsible for the financial management, correspondence and organization of all assembly activities.
