Mark Rider, Ph.D., M.S. Psychopharmacology


Dr. Mark Rider has been a licensed psychologist in Southlake, TX for over 20 years.  He has post-doctoral training in Neurotherapy, EMDR, Cognitive Hypnotherapy, and Psychopharmacology.  His first book, The Rhythmic Language of Health and Disease (1997), demonstrated that neuroplastic shifts in the brain can be created by music and imagery, and were essential for health.  His next book, Revisioning: Mirror Therapy for Unresolved Grief (2014) revolutionized the treatment of complicated grief.  This technique has been shown to be 99% effective with this condition.  Together with Lynn Heselton, their latest book, Revisioning: Rapid Mirror Neuron Psychotherapy for Grief and Trauma, has created groundbreaking treatments for PTSD, Personality Disorders, and Dissociative Disorders without the client having to relive the traumas.  Mark is currently director of the Revisioning Center for Grief and Trauma.
