Function your best.

Find the root cause in your brain.

Brain ARC provides evaluation, education and consultation services that incorporate research and technology.

These services are aimed at determining the root causes of less than optimal brain patterns to help patients select the treatments that will help them function their best.

Seeking to understand how their brain works and how it can be helped to work better.

What are the benefits?

Traditional western medicine looks at symptoms to help us feel better. Research conducted by our partners has shown that understanding how the brain works can provide insights that guide a course to help improve how efficiently our brain works, to help reduce unwanted symptoms (ie., impulsivity, anger, anxiety, depression, etc.)


Seeking to understand how a student’s brain processes information.

What are the benefits?

There is extensive research that helps us understand the brain’s role in attention, processing, reading and behavior problems, as well as many more concerns that impact academic success. The most frequently used neuropsychological testing tells us about performance, but not the source of the problem. Our testing identifies how the brain processes and where the inefficiencies originate, so they can be corrected.

Medical Providers

 Seeking biomarkers to assist in selection of medication and other treatments.

What are the benefits?

Use functional neuromarkers to guide treatment and predict response to medication based on empirical research.

Why a Brain ARC assessment?

A Brain ARC assessment includes an electroencephalogram (EEG) that is read by a neurologist and incorporates analyses derived from the EEG (Functional EEG and Evoked Potential Analysis (ERP). These measurements give the only true direct measurements of how the brain functions and are obtained in three conditions: eyes opened at rest, eyes closed, and during a task.

Who are we?

Our board certified staff is actively involved in research, teaching nationally and internationally and consulting to other professional offices. Our offices have been chosen by HBImed and BeeMedic, international leaders in the field of neurofeedback equipment and data base developments, to be the partner offices in the United States and Mexico.

Our staff has been training biofeedback since 1999. We are one of the few providers in the US who specialize in evaluations and have extensive experience with biofeedback and neurofeedback training. On the average, our providers have conducted hundreds of evaluations and treated thousands of patients. We work closely with researchers in Switzerland to incorporate the most up to date research in our processes so that patients can recieve the benefit of more individualized treatment that will help them attain success as quickly as possible.

Angelika Sadar


Angelika is a psychologist that has been in private practice since 1987. Once introduced to neurofeedback, I found the knowledge of the brain provided a tool to help patients change in a way that had often taken years with psychotherapy alone. Since 2006, I have treated thousands of patients and have presented at numerous events to train other clinicians in this method.

BrainARC Chur

Located in Switzerland.

The collection of the normative HBI Data Base was initiated by the Swiss psychologist Dr. Andreas Mueller from the Brain and Trauma Foundation. He was inspired by the QEEG/ERP methodology which Jay Gunkeman and Juri D. Kropotov were teaching. Dr. Mueller and the staff at BrainARC-Chur opened the first of the offices in Switzerland to implement the methodology of BrainARC personalized medicine.

Mirret M. El-Hagrassy, MD

Mirret M. El-Hagrassy, MD, is a licensed neurologist, board-certified in Neurology and Epilepsy. She is currently a post-doctoral research fellow at the Spaulding Neuromodulation Center, Harvard Medical School. Dr. El-Hagrassy is conducting research and training in neuromodulation with an emphasis on neurologic disorders, and her current research projects involve the effects of non-invasive brain stimulation on Parkinson’s disease, chronic pain as well as EEG changes in healthy volunteers.

She has co-authored book chapters and papers (in press) on clinical research and non-invasive brain stimulation. Dr. El-Hagrassy has a special interest in non-invasive brain stimulation, EEG, epilepsy, and neurofeedback. She enjoys living and working in multicultural environments and multi-specialty groups.

Dr. El-Hagrassy completed her medical training at the Faculty of Medicine, Cairo University (Cairo, Egypt) over a decade ago, and has moved to the US since. She completed her neurology residency at SUNY Upstate University Hospital (Syracuse, NY), clinical neurophysiology (EEG and Epilepsy track) fellowship at Cleveland


The HBimed database is the most advanced and largest database of its kind, powered by Swiss precision. The HBimed methodology allows for analysis of the working brain by looking at the information flow and comparing it to its normative database. HBImed has performed extensive research in this field and has defined parameters of quantitative electroencephalogram (QEEG) and components of event-related potentials (ERPs) as highly specific biomarkers for a variety of mental disorders.


FDA approved , EEG equipment targeted to ultra precise measurement of how the brain processes sensory input. BEE Medic is part of an international group of companies that maintains close cooperations with clinical operations and research institutions, aiming to provide practical instruments for therapy, diagnostics and research.

When acquiring erp data, timing is essential. Independent analyses have shown the BeeMedic equipment has the exact timing necessary for accurate comparisons with the data

Meyer Proler, M.D.

Dr. Proler is a leader in telehealth and eminent in the field of neurophysiology. He pioneered remote neurology in the mid 1970s by interpreting patient EEG test results transmitted over standard phone lines. He earned his M.D. at Baylor College of Medicine, where he also did his fellowship in clinical neurology. Dr. Proler was Clinical Assistant Professor of Neurology at Baylor College of Medicine from 1980 to 1994 and was offered the Chair of the Department of Neurology but declined the position to go into private practice.
