Neurofeedback Course Testimonials

“I have attended many neurofeedback seminars with Dr. Mary Tracy as the Instructor for STENS Corporation, including the 5 Day Professional Neurofeedback and QEEG course, which covers such topics as Neurofeedback and Multi-Modal Biofeedback, HRV Training, Demonstration of Client Assessment utilizing the New Q, Single or two channel SMR, Beta Training, Alpha Theta Training, Understanding EEG tracings, and How to do two or four channel Z-Score Training to name a few important topics.  Further, I have taken the Advanced 5 Day QEEG Professional Certificate Program.   DR. Mary Tracy is an excellent Instructor, covering the most salient topics in a brilliant manner and with humor.  Dr. Tracy teaches both courses in a brilliant manner, focusing very heavily on the science behind neurofeedback.  In addition, Dr. Tracy discusses practical examples of protocols that work very well to address clinical issues in order to improve brain regulation, and optimal functioning.”

"After upgrading from a Nexus-10 Mark II to a Nexus-32, I recently attended the Stens 4-Day Professional EEG/QEEG Neurofeedback Certificate Program and the 1-day Intermediate Hands-On Practicum Course. With a Nexus-32 on hand for demonstrations and to practice with, the didactic and hands-on experiences at both trainings were exceedingly helpful.  I felt significantly more confident using the Biotrace software and the Nexus-32 after attending both courses and highly recommend them for anyone wanting to learn more about neurofeedback and QEEG and/or needing more experience using the Biotrace software and Nexus hardware.  Additionally, the tech support offered by Stens before and after the training have been essential in helping add biofeedback, neurofeedback, and QEEG services to my therapy practice. I am extremely satisfied with my experiences with Stens as a whole."

“Mary Tracy is an excellent neurofeedback trainer and QEEG instructor with a deep knowledge of how to read EEGs and practice neurofeedback that comes from years of experience.  She aptly applies her knowledge in the classroom context and translates concepts and protocol to new, and experienced, practitioners in an accessible and engaging way.  I took her QEEG class and benefited greatly from her expertise, hands on approach to learning, her patience, and the thoroughness of her instruction.  You will come away from the class surprised by how much you learned in one week and excited to apply what you learned.”

"John (Anderson) is a great instructor and I am glad to be re-taking the EEG course as an assistant for FREE. It makes much more sense after having been working with the equipment for a while. It is necessary to attend more than once, in my opinion, and it is a good business practice that you allow for this. There is no other workshop that I know of that allows this without paying an additional fee. I would also like to mention that after having worked a bit on the other systems in the workshop this time, I am happy I purchased a Nexus."
