Gloria Crook started studying the Wisdom Teachings at age 14. She is 90 now. In 1977 Gloria founded the School of Ageless Wisdom, which offers classes on the Teachings of Masters D.K., M. and R. and holds Public Full Moon Meetings. All classes are held at the School's property on Lake Arlington, in Texas.
The Exoteric Service of the School is the "Model United Nations for Elementary and Middle-School children, with High-School children as Secretariat. All three Masters recommend support for the United Nations as the One Entity where all Nations meet to solve world problems. The "Global Elementary Model United Nations”(GEMUN) came about as a result of implementing Dr. Robert Muller’s "World Core Curriculum” for 16 years, after Gloria founded the first "Robert Muller School” for the children of the Ageless Wisdom students to attend.
