Mark Smith

Clinical Instructor

Mark Llewellyn Smith is the owner and Clinical Director of Neurofeedback Services of New York. He is a licensed clinical social worker, whose early career was established in the world of work, providing clinical services to the nurses, doctors, and staff of NYU Medical Center and Downtown Hospital in New York City. Due to his proximity to the Twin Towers at Downtown Hospital, Mark spent many years following 9/11 working with first responders and their families. He developed psychophysiological interventions that included neurofeedback and biofeedback for those with PTSD and CPTSD. That experience put him on the path to developing a trauma focus in his practice. In private practice since 2000, Mark is a leading developer, teacher, and clinician of neurofeedback interventions for a variety of disorders. Infraslow Fluctuation (ISF) training, now a primary intervention in EEG biofeedback therapy, was developed by Mark from his experience training the “Ultradian” rhythms: the lowest energy the brain produces. This type of neurofeedback has had a profound, positive impact on the lives of his clients, as well as, the clients of the hundreds of therapists he has taught in the last decade. Mark was also an early adopter of sLORETA neurofeedback training. This experience, memorialized in publications, led to the development of a 19- channel ISF intervention and the research collaboration with Otago University and Dirk De Ridder, MD, PhD. He was among the first to use Z-score training in clinical practice. As an early adopter and developer of Z-score training, he worked closely with several manufacturers in the neurofeedback community to develop Z-score neurofeedback interventions for a host of clinical presentations. QEEG or brain mapping is an integral part of Mark’s approach to psychophysiology. He has taught QEEG in Europe, Asia, on the continent of Africa, and throughout the United States. He has been a mentor to scores of clinicians who seek Diplomate status in this analytic process.
