Smith began researching the UFO phenomenon in the late 1980's and in 1990 [after 2 years of studies and 1000 hours of internship] received her certification from the California Hypnosis Motivation Institute. In 1990 she expanded her practice to include "abductees," assisting them and encouraging them to work through and cope with their PTSD. [Many of her subjects are referred to her by physicians and psychologists.] In 1991 Yvonne founded CERO [Close Encounter Resource Organization] which maintains active monthly support group meetings where abductees share their thoughts and feelings about their unusual experiences.
