Michael D. Yapko, born August 5, 1954, is a clinical psychologist and author whose professional work centers on treating depression, developing concise psychotherapeutic methods, and expanding the clinical uses of hypnosis. He earned his degrees in psychology from the University of Michigan and United States International University, and is licensed in California as a psychologist and marriage and family therapist.

After maintaining a private practice from 1979 until 2007, Yapko shifted his focus to writing and teaching. He has directed The Milton H. Erickson Institute of San Diego and served on the editorial boards of several prominent journals related to hypnosis and psychotherapy. His academic career included faculty positions at National University and United States International University. Yapko also contributed a regular column to Psychology Today and currently serves on advisory boards for major clinical hypnosis publications.

Yapko is known for his application of Ericksonian techniques, particularly using hypnosis as a non-pharmacological approach to treating depression. He views depression as a complex disorder influenced by biological, psychological, and social factors, often favoring psychotherapy over the overreliance on antidepressants. He also gained attention for his views on repressed memories, suggesting that some therapists may inadvertently implant false memories of abuse through suggestive techniques.

Michael D. Yapko is a prominent advocate for the use of clinical hypnosis, particularly within the framework of Ericksonian approaches, for treating depression. He posits that depression is a multifaceted condition, influenced by a combination of biological, psychological, and social elements. Yapko suggests that psychotherapy is often a more effective treatment modality for many individuals, and he expresses concern that antidepressant medications may be overprescribed without a full understanding of their long-term efficacy or potential side effects. His approach emphasizes integrating various therapeutic strategies to address the complexities of depressive disorders.

During the 1990s, Yapko became a figure of controversy within the mental health community due to his assertions about the potential for therapists to inadvertently implant false memories of childhood sexual abuse in patients. He conducted a survey of nearly 1,000 therapists, reporting that a significant percentage believed they had encountered cases where trauma memories were suggested by the therapist rather than stemming from genuine experience. Yapko also highlighted a lack of specific training in clinical hypnosis among therapists who used such techniques, which he viewed as a serious concern. His 1994 book, 'Suggestions of Abuse: True and False Memories of Childhood Sexual Trauma,' explored these issues, detailing how certain therapeutic methods, including symptom checklists, could lead to the diagnosis of abuse that may not have occurred.

Yapko's extensive contributions to the field of clinical hypnosis and psychotherapy have been widely recognized. He is a recipient of multiple Arthur Shapiro Awards for his books on hypnosis and depression, as well as the Milton H. Erickson Award of Scientific Excellence for Writing in Hypnosis. Further accolades include the American Psychological Association's Division 30 Award for Distinguished Contributions to Professional Hypnosis, the Pierre Janet Award for Clinical Excellence, and a Lifetime Achievement Award from The Milton H. Erickson Foundation. He has authored over a dozen books, numerous articles, and has had his works translated into nine languages, solidifying his status as a leading authority in his specialized areas.
