Conditions we treat

LENS Therapy can help treat the following conditions:


LENS Therapy helps re-train sensory skills that may have been missing or incomplete in early brain development

Anxiety & Stress

LENS Therapy unlocks stress patterns, helping you focus and deal with everyday life without tension or anxiousness


LENS Therapy helps the brain break out of these involuntary habits and allows us to shift back into a more balanced mental and emotional state.

Migraines & Headaches

LENS Therapy calms the brain to a normal state, lowering the brain wave amplitude and frequencies that cause tiredness and intense headaches that come with these conditions.

Sleep Disorder

LENS is proven to help quiet the brain, allowing the body to sleep better, restore your natural sleep rhythms, and assimilate stress easier.

Concussion & TBI

LENS Therapy works at a deep subconscious level, breaking the cycle of concussion and post-traumatic symptoms.

How LENS Therapy works

A sensor is placed on each ear, while another is moved to different areas of your head. A low energy radio wave is sent to the brain, disrupting the negative pattern, and allowing the brain to find an easier, more efficient, and natural pattern.

Each sensor is in place for about 20 seconds each; most people won’t feel anything, while occasionally some may feel a slight tingling sensation to the area.

The total process lasts about 4 to 5 minutes, and you are not required to “do” anything other than sit and be relaxed and comfortable.

These invisible frequencies emit less energy than a standard cellphone.

LENS Neurofeedback, is quick, painless and requires no involvement, training or testing by the recipient.

Recent reviews from our clients

I have had emotional trauma in childhood and 7 concussions. So far, I’ve done the mapping and just now my second treatment, all the static and chaos in my brain are gone. I can hear my thoughts, I can sit in peace and quiet, I can breathe! I can’t even imagine how much better things are going to be as treatments go on!

Karen Elizabeth

Truly innovative brain treatment that western medicine doesn’t offer. This can optimize your life. Sheri and Denise are very welcoming and make you comfortable. I highly recommend to anyone. You can try a first mapping session and see what you think!

Ben Garrison

My experience with Shari has been a subtle miracle. Less anxiety, better sleep, clearer thought processes, ability to stay centered —- all the things that make the difference between a blah day that I drag myself through and a productive, rewarding day. I am so grateful to Genia and my daughter for leading me to Shari and a harmonized brain.

Tanya Miller Fore

I am a cancer survivor who couldnt recall multiplications nor form complete sentences without struggling after chemo. Sheri at Harmonized Brain Centers cleared my chemo fogwithin a few treatments!!Though my clarity has improved, headaches are gone, short term memory works better, its really the personal coaching, patience, and genuine desire to help clients improve that makes Harmonized Brain Centers of TN wonderful. Want to improve your brain function, this is the only place/thing I would recommend!

LaDonna Lacy Hix

Sheri is knowledgeable and professional while being warm and welcoming. I am having fewer and milder headaches since beginning LENS Neurofeedback. Thank you!

Vickie Calhoun

Words will never be able to express how much we appreciate everything that Sheri at Harmonized Brain Centers has done for our son. After years of anger outbursts and inability to maintain friendships, he is back to being the amazing boy he used to be. Sheri not only provided the LENS but she helped coach him into making better choices in both his home and academic life. Kudos to no drugs and positive results!
