Director of Neuro Therapy Dr. Nicholas Dogris, Ph.D., BCN, QEEG-D, has been working in the field of neurostimulation and neuromodulation for about three decades as a clinician, researcher, and innovator and developer. He has had the rare privilege of working with some of the first founders of neurofeedback to develop new innovations in the field.

Dr. Dogris’ invention of the first synchronized, neuromodulation and neurostimulation system, “NeuroField,” has earned him national recognition as a leading expert in the field. The NeuroField system, (which we use at Sun Health), has helped many patients achieve better brain health, relief of withdrawal and mental health symptoms, and peak performance. The system utilizes normed referenced data, QEEG analysis, and a combination of pulsed electromagnetic fields (pEMF) and transcranial alternating/direct current stimulation (tDCS/tACS) to successfully treat many neurological problems.

As a clinician and researcher, Dr. Dogris is continually developing and improving new protocols for the NeuroField system, with the goal of helping more patients better address their specific symptoms. So far, he has developed 200 such protocols, and Sun Health patients are among the first to reap the benefits. Among them: reduced cravings, decreased anxiety and depression, and renormalization of sleep patterns. pEMF, tDCS, and tACS have been found safe and effective in treating depression, ADHD, addiction, insomnia, and traumatic brain injury, among other disorders.

A licensed health psychologist and neuroscientist, with board certifications in neurofeedback and quantitative electroencephalography (QEEG) analysis, Dr. Dogris first started in the electroencephalography (EEG) field when he was a student at Humboldt State University in 1987. At the time, he was working on P300 research.

Today he holds four advanced degrees, including a Ph.D. from the California School of Professional Psychology. He has worked with a wide variety of mental health populations, including children, adolescents, and adults, and has held positions as the Program Chief of Mono County Mental Health, Orange County Mental Health, Inyo County Mental Health, and College Hospital.
