My Story

Hi, I'm Sara Silveira and I'm passionate about helping others; it brings me joy and purpose.  That is why I'm so excited to bring NeurOptimal® to the Central Valley to offer to our community the amazing benefits of this life-changing technology and joining them on their journey to happiness and well-being.    

Through my experiences as a Special Education teacher over the past 12 years and as a volunteer in the Philippines, I've developed a love of working with people of all ages to help them overcome obstacles and achieve personal success. 

Now, as an advanced NeurOptimal® trainer, I am seeing the positive change that NeurOptimal® has on others and I want to share the benefits of this powerful tool with our community. It is my hope to be able to empower you to achieve your greatest mental, emotional, physical, and spiritual health.

What is Neurofeedback?

NeurOptimal®’s EEG biofeedback or neurofeedback system is a powerful technology that can greatly enhance your well-being and generally help you get the most out of life. Brain training can unlock untapped cognitive potential and help you achieve long-held goals and dreams. Biofeedback has been around for almost 40 years, but its practical use was inhibited by the scarcity of a practical delivery system. In the past, a neurofeedback interface would require a room full of computers and technicians. Today, Zengar Institute, Inc. has created a simple, interactive software that harnesses this powerful technology in an easy to-use program called NeurOptimal® that loads onto a laptop computer. Because neurofeedback has been time-tested, it is also very safe. Respected institutions such as the U.S. FDA and the American Academy of Pediatrics have endorsed neurofeedback.

What is NeurOptimal®?

The NeurOptimal® proprietary neurofeedback system is a highly personalized brain training software that prompts the central nervous system to help make the best use of your brain’s neural resources. Neurofeedback training for the brain is similar to physical training for the body. Much of our suffering comes from pervasive recurring thoughts and feelings in which our minds become emotionally stranded or cognitively “stuck”. Neurofeedback prompts the brain to draw from its existing resources and pull itself out of these mental “ruts”. The result is a more open and positive mindset in which obstacles are more manageable and problems more resolvable. Much like a mirror that promotes self-correction, NeurOptimal®’s proprietary neurofeedback program monitors your brain waves and then provides “feedback” to your central nervous system about what it has just done, invites the brain to the present moment, disrupts  patterns of instability, and allows the brain to reorient itself.  It is through this training process that the brain promotes flexibility and improves resiliency.

why use NeurOptimal®?

NeurOptimal® is extremely powerful and effective. It is safe with no side effects, it is 100% non-invasive, it provides a natural way for the brain to reorganize itself to its balanced and optimal state with no effort on your part, and the results are long lasting.  Neurofeedback training provides a multitude of benefits for the brain and body, including: improved sleep, heightened mental clarity and enhanced cognitive performance. The U.S. Food and Drug Adminstration has approved neurofeedback for relaxation training and the American Pediatric Academy has endorsed neurofeedback as a “Level 1/Best Support” treatment for children with ADHD.Trainers and clients –millions and growing- have used the NeurOptimal® system to address a number of physical, emotional and cognitive complaints with great success. 

Transforming lives through NeurOptimal®





NeurOptimal® neurofeedback encourages an overall positive mental outlook and a deeper understanding of the mind/body connection. For those looking to enhance their daily health and wellness, neurofeedback training can be an excellent supplement to a healthy diet and exercise routine.





Adults, as well as children, have used NeurOptimal® neurofeedback to address the negative effects arising from depression, anxiety, PTSD, Alzheimer’s, autism, sleep disorders, and other complaints. The FDA has even approved neurofeedback as effective for stress reduction.

Along with healthy lifestyle choices, NeurOptimal® neurofeedback can be a powerful tool to mediate cognitive decline that naturally occurs as we age. Just as physical exercise benefits the body, NeurOptimal® keeps the brain fit and resilient. Neurofeedback can help improve memory, recall and increase overall cognitive dexterity in older individuals.





A growing number of Olympic and professional athletes now use neurofeedback to provide that critical mental edge which often results in gold medals and championships. But you don’t have to be a pro athlete to enjoy the benefits of neurofeedback. NeurOptimal® can help.





Because neurofeedback training enhances concentration and mental focus, students use NeurOptimal® as a critical tool to improve their performance in school.  NeurOptimal® is 100% drug-free and has no known side effects. 

Frequently Asked Questions

Is NeurOptimal®safe?

 Research shows your own brain “knows best” and therefore the NeurOptimal® brain training system does not force or “push” the brain in any one direction. Basically, Dynamical Neurofeedback® provides your brain with the information it needs to correct itself and function at its most optimal. NeurOptimal® simply enables your own brain’s natural process of self-correction.NeurOptimal® is exceptionally safe and without any side effects.  NeurOptimal® has provided brain training to the public for the past 17 years and has well over three million hours of safe usage.

Is brain training invasive?

No, NeurOptimal® is entirely non-invasive.  Sensors are temporarily attached to your head and ears to only monitor cortical activity.  It does not attempt to “fix” predetermined conditions or pin down specific problems by augmenting or suppressing any frequencies.  It merely, serves as a mirror by providing direct feedback to the brain.


Will I have to do anything?

NeurOptimal® requires no effort on the user’s part. Some brain training systems require the user to “interact” by playing games or solve puzzles during sessions. This additional level of interaction is unnecessary with the NeurOptimal® neurofeedback system. During a training session, you can simply relax and enjoy!

How many sessions does it take to feel a difference?

Each person is different and unique.  Some people feel an instant improvement, others feel it after 5 or 6 sessions, and still others after more sessions. The human body and the brain in particular operate in nonlinear ways, so we suggest that users have an open mind and stick with regular brain training to see results. We recommend a minimum of 10 sessions as a baseline for brain training.

What sorts of differences will I start to feel?

The first thing most people notice is a substantial improvement in the quality of their sleep, particularly more vivid dreams. After a few sessions users often feel more focused, calm, and centered. With continued training people report more confidence, productivity. They begin bouncing back from stressors with ease, and report that life generally becomes smoother. Users work faster, more efficiently, and experience a significant reduction in physical complaints. They are less bothered by doubts and insecurities and are more apt to experience confidence and satisfaction.
