About us

Neurofeedback (NF), or EEG biofeedback, has been practiced for well over four decades. Hundreds of thousands of individuals and families impacted by various mental health and/or neurological conditions have benefited greatly from this powerful, effective, established, and proven intervention. NF is relatively non-invasive and creates lasting results in stark contrast from the outcomes derived from pharmaceutical treatment for a wide variety of conditions. We estimate over 15,000 clinicians, world-wide are using this technology. The represented professions are inclusive of: psychology, counseling, social work, marriage and family therapy, nursing, neurology, pediatrics, rehabilitation medicine, physical therapy, occupational therapy, naturopathic medicine, speech and language pathology, chiropractic, psychiatry, child and adolescent psychiatry, and family medicine.

Our approach

Empirical Studies from Universities, hospitals, Neuroscientist, Doctors, Psychologist & Engineers for the last 70 years are now evidently effective.  Many have tried other therapies and finally they try neurofeedback.  Better still ISF neurofeedback.   Many have told me, “I wished I started first with QEEG Neurofeedback, either to save time or money. Simply put, many therapies tried to activate speech from zero sounds/speech via speech therapy, Sonrise and ABA, and have not been successful when the network is not connected.  We have taken on these cases and succeeded to activate speech for these kids.  As a ‘Behavior Psychologist’ ( since 1991), I know when ABA can or cannot work, and if intervention is introduced at the wrong time.  This is simply the power of the schedules of reinforcement applied in all therapies even if they do not know it.  This differentiates a good therapist from the rest.   Correct schedules contributes to the effectiveness of neurofeedback therapy too.  When to change the frequencies and when to introduce a different protocol.   All therapies like Sonrise, ABA, Speech therapy are good and will work better when introduced at the appropriate time, when the brain is ready.  Qeeg Neurofeedback is able to do this because we scan the brain and know where and when to treat the brain.  We have replicated success many times.  The brain is like a network of radio stations.  If you want to attain frequency  FM90.5, you have to accurately tune 90.5 to get loud, clear sounds.  Because neuroplasticity exist, the road to recovery exist.  We may be the road less travelled but surely real hope begins with us.

Neurofeedback Societies Maintaining Research Bibliographies

  • The International Society for Neurofeedback and Research maintains a comprehensive bibliography of research articles discussing conditions that are positively affected by neurofeedback by D. Corydon Hammond, Ph.D., Professor, Physical Medicine & Rehabilitation, University of Utah School of Medicine, and D. Allen Novian, Ph.D., LMFT, LPC-S, Adjunct Professor, Neurofeedback and Biofeedback, St. Mary’s University. ISNR also has an editorial in defense of EEG biofeedback.
  • The Association for Applied Psychophysiology and Biofeedback published Evidence-Based Practice in Biofeedback and Neurofeedback (3rd ed.) which provides the most comprehensive and up-to-date evidence-based and neuroscientifically supported information on the subject. They also have more information for consumers.
