Dr. Annon was a Life Fellow of the American College of Forensic Examiners International and a Diplomate of the American Board of Forensic Examiners, American Board of Forensic Medicine, and the American Board of Psychological Specialties. Annon received his PhD in clinical psychology in 1971 from the University of Hawaii, where he also earned his master’s degree in counseling psychology and his bachelor’s degree.
He was active in psychology in Hawaii and served as president of the Hawaii Psychological Association as well as on the state licensing board in Honolulu for 8 years, mostly as its chairman. He was also a member of the Council of the American Psychological Association and on boards of other national psychological associations.
His practice was devoted to forensic and criminal psychology, though he did some civil work as well. His career in forensic psychology earned him honors and kudos worldwide in the field. His publications number in the hundreds and have impacted almost every area of specialization, from general ethics to such specialized areas as the assessment and treatment of sexual offenders. Since its introduction in 1971, Annon’s PLISSIT model has been in continuous use by general and specialized practitioners all over the world.
In early 2005, ACFEI honored his many achievements in the association, as well as the field, with its Lifetime Achievement Award. He passed away later that year.
