The Institute for Reality Therapy was founded in 1967 by Dr. William Glasser, lecturer, author and board-certified psychiatrist, as a response to the requests by professionals for formal training in  Dr. Glasser’s counseling method, reality therapy.  In 1994, The Institute was renamed The Institute for Control Theory, Reality Therapy and Quality Management to reflect the scope of The Institute’s teachings. Two years later it became The William Glasser Institute with Dr. Glasser renaming his theory, choice theory.
