Our Team

Mark Smith

Mark Smith, LCSW, BCN, QEEG-D

Founder / Owner

Mark Smith 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. He is the owner and Clinical Director of Neurofeedback Services of New York.

In private practice since 2000, Mark is a leading developer, teacher, and clinician of neurofeedback interventions for a variety of disorders. He was the first to use Z-score training in clinical practice. As an early adopter and developer of Z-score training, he worked closely with Thomas Collura of Brainmaster Inc. and Robert Thatcher from Applied Neuroscience Inc. to develop Z-score neurofeedback interventions for a host of clinical presentations. These protocols are arguably the most frequently used interventions in Z-score training worldwide.

Infra-slow 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 several years. For the last two years, Mark has contributed to the establishment of sLORETA training with Thomas Collura and others.
