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.

    5 star review  I have known Mark Smith as a clinician and instructor for fifteen years. He is open, candid, and professionally dynamic. An intensely knowledgeable practitioner, he has managed to develop a unique form of treatment and neurofeedback training that has been shown to achieve splendid results. He is intellectually honest and persistently refines his knowledge and techniques. His willingness to work with clients with complicated and chronic problems that other professionals have been unable to help is a testament to his dedication, determination, and compassion.

    5 star review  Neurofeedback has been a life-changing journey for me. I’ve had sleep problems since I was a kid, and for the first time in two decades, they finally feel manageable. Additionally, it’s reduced my overall anxiety to a staggering degree, and I’ve felt my overall alertness and creativity go up. Grateful for Mark, Noel, and Leila’s support.

  • 5 star review  I have only been performing ISF training for a few months, but I can say it is my personal and clinical opinion that this is probably the most powerful intervention ever known. With ISF, I have been working with people who thought they were beyond hope. They are getting significantly better, and finally getting back into the life they deserve. Mark Smith used the word “glücklich” in the ISF workshop, meaning that feeling of total euphoria, peace and happiness that sometimes comes upon someone during the training. I have not had this happen during my own ISF training, however I have lived this feeling in a very clinical way for the last few months because I am helping people in ways that I never dreamt possible. Each day I witness miracles. I have seen people that have been so depressed that they were frequently admitted to the hospital for suicidality. Now they're happy and going back to work or school. Clients with balance problems and mobility issues are walking again. A couple of my clients had asthma that interfered with their lives and sports performance, and now the asthma is gone. Other clients have had horrible gastric intestinal issues to the point where their lives revolved around accessing the bathroom or taking medications just to have normal bodily functions. These people have minimal gastric intestinal issues now. Two of my young clients have had horrific development trauma and are now playing and dancing like other children do. I spent thirteen years working in an inpatient psychiatric unit and saw some of the most dysregulated brains imaginable. Now I have some of these people in my private practice and they are getting better. I would not believe any of this unless I would have seen it on first-hand basis. It just doesn’t seem possible. On a personal note, my daughter had three concussions a few years ago. She spent a couple of years in bed and thought her life was beyond hope, then we discovered neurofeedback. She has had many sessions of surface neurofeedback training (both one channel and four channel Z score) and got her life back, but her gastric intestinal issues, temperature regulation, asthma, and sleep issues still lingered. Since she has been optimized through ISF, she is sleeping well, does not have asthma, and is eating foods that she was never able to eat before. Her GI functioning is fairly normal. I don't know that I can actually find the right words to express my feelings about ISF. Each day I experience “glücklich” because I witness miracles happening in the lives of others. I am very blessed to be providing this amazing treatment. Thank you Mark and all the others who have made ISF possible. We are changing the world, one client at a time.

    5 star review  In my opinion, Mark Smith and his staff should be the first call for treatment of ADD, ADHD, ODD, depression, anxiety, trauma and migraines. He is kind and patient, not to mention very well trained and overall a great clinician. I have used Mark as a resource several times in my own practice. If you are in or near the city and have any interest or questions regarding neurofeedback, I would highly recommend reaching out to Mark before you go anywhere else.

    5 star review  I can tell you that I am a completely different person in all the best ways possible. To those who "poo poo" this, you have no idea how much better your life could be. Depression is almost non existent. I feel like a new person.
