Stens Educational Mission

Our mission is to empower healthcare professionals worldwide by providing the best biofeedback, neurofeedback, and QEEG educational programs. We combine hands on experience using state of the art technology.

Stens Professional Certificate courses provide knowledge of and experience with instrumentation and present models of clinical application which are current and efficacious.  Our approach to achieving these goals is both didactic and experiential. We believe that learning is maximized within an environment that is supportive and nurturing.

Our core curriculum is specifically designed to provide a clear model that allows immediate use with disorders and explores other innovative directions.  It is a step-by-step learning process that requires no previous experience with either biofeedback instrumentation or computers.  The program provides an incomparable learning environment for the beginner and allows more experienced practitioners to pursue more advanced application.

Through the presentation of current and relevant clinical material, combined with ample time for self-experience and practice, our trainees can successfully integrate biofeedback & neurofeedback into their own clinical style and approach.

Neurofeedback & qeeg instructor


As a student of holistic and traditional healing methods for more than 30 years, I have worked to blend this knowledge and experience with the most current research in psychology, neurophysiology and developmental neuro-technology. My goal has been to create a powerful, effective method for change.

I began working with biofeedback and neurofeedback in 1974. My clients have included children and adults with ADHD and other learning problems, chronic pain, addiction disorders and much more. I currently maintain a private practice, provide consulting services for new and existing neurotherapy programs and work as an instructor, training others to become neurotherapy practitioners.

My masters degree is in psychology. I am licensed as an alcohol and drug counselor and certified in biofeedback and neurofeedback by the Biofeedback Certification International Alliance (BCIA).
