Frank Anderson MD is a psychiatrist, trauma specialist and author of Transcending Trauma and Internal Family Systems Skills Training Manual. He is lead trainer and consultant for the IFS Institute, an advisor to the International Association of Trauma Professionals (IATP), and maintains a private practice.

Frank trained in psychiatry at Rush University Medical College in Chicago. During his residency at Harvard Medical School, he realised that many of his clients struggling with major mental illness had also experienced significant trauma in their lives. The pain he witnessed in others activated something deep within himself, compelling him to enter therapy, which quickly connected him to his own trauma history.

He served as a psychiatrist at the Trauma Center in Boston under the direction of Bessel van der Kolk. After a meeting with Richard Swartz, the founder of Internal Family Systems, he integrated his knowledge of neuroscience and trauma treatment with Internal Family Systems (IFS) therapy.
