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!


HBC and especially Sheri have been a blessing and a lifesaver! Sheri is amazing and has helped in ways I never would have imagined! She is so very kind, thoughtful, understanding, and helpful! If you are considering HBC do not hesitate, it will change the world you are currently stuck in! Make the call, make the appointment it will change your life! Thank you, Sheri, for all you have done!

Kent DuMont

Harmonized Brain Centers has changed my life! I’ve been on ADHD medication my entire life, and the side effects from the medication have caused eating issues, mood swings and a desire to always be alone. I’ve only had two sessions so far, but I’ve already seen such a change! Not only do I feel entirely better being off the medication, but my focus has gone up dramatically, giving me so much more motivation to go to work, to read (I never read before), and to socialize with my friends and coworkers. Thank you, HBC, for helping me create a better way of living. I can’t wait for my next session!

Shelby Ann Muir

Thank you for the treatments! I am already feeling so much more focused and clearer headed. Slept great and feeling good. I’m a Licensed Mental Health Counselor in Florida and after meeting with Sheri, I find her to be highly knowledgeable and professional! Can’t wait for my next treatment!

Christina Rooney

Harmonized brain canters have changed my life! I am a traumatic brain injury survivor and have noticed so many changes in my brain and body with LENS! I have done quite a bit of treatments and have noticed that the little things that happen in the workplace such as dropping glasses on the floor and hearing them shatter used to make me feel embarrassed and anxious really bad, but after doing treatments with LENS I am able to realize what just happened and not get anxious and quickly clean up the mess and get back to work! The treatment in LENS IS VERY EFFECTIVE and is very quick to treat whatever your symptoms are such as ADD PTSD ANXITY AUTISM! I would recommend giving this treatment a try.

Austin Shepard

We have been going to Harmonized Brain Center for a little over a month and we couldnt be more pleased. Our family has all done treatments and we recommend for anyone. Kathy is our therapist and we have so far had a wonderful experience!

Charlie Faulkner

Harmonized Brain Centers is a great place!! Highly recommended for those with anxiety, depression, ADHD and even more. I took my daughter there with anxiety and ever since she started the treatments, she has been enjoying her time with feeling anxious or any pain. The people there are nice and make you feel comfortable and safe! My experience there was amazing and would highly suggest going if you need help.

Irene Vargas

Excellent treatment of anxiety related behaviors. Wonderful experience, with helpful staff and a calming office environment. Would 10/10 recommend.

Rachel Rowney

Cant recommend HBC enough! The staff are caring and welcoming, and the brain treatments are very effective in managing anxiety and depression.

Potter Ray

I am so happy I discovered Harmonized Brain. Both my husband and I have stressful careers and it took a toll on our relationship. Harmonized Brain saved our marriage, it has allowed us to heal and improved as individuals and be able to reconnect as a healthy couple. Don’t think about it twice!! It will change your life for the better.

Janet Abeja

The treatments are painless and quick, and Sheri is amazing at explaining everything to you and how it works! It has helped me a lot with my anxiety, and I highly recommend going here!

Delaney Fore

I can’t say enough good things about Sheri and the Harmonized Brain Centers of Tennessee.  I had been having a tough time with anxiety, and accidentally stumbled across the Harmonized Brain Center.  I had attended support groups, read books, tried meditation, exercise, etc.  Nothing seemed to curb the anxiety monster that had been maligning me.  Sheri did an incredible job at walking me through the process and breaking it down into comprehensible pieces so that me, the layman, could understand.

I began to see changes after just a few sessions, and by the end I felt like an entirely different person.  It’s interesting looking back at my demeanor prior to my LENS sessions, and how it and my outlook have changed so dramatically.  I feel more in control of my mind and my life.

I truly believe that LENS can be beneficial to almost anybody.  We all have things that vex and compromise our thoughts and mind on a daily basis.  We sacrifice our mental care through overexertion and push ourselves to the brink until we break.  I am convinced that this is where my anxiety came from.  LENS made it possible to “reboot” and bring my brain back to a state of normalcy and control.  I am and will be eternally grateful to Sheri and her team for mending the mind of an anxious man.

Jones Nelson

Great experience; fantastic results.  It’s been 3 weeks since I finished all my treatments with Nana, and I am thoroughly impressed.  She was very informative and took great effort to customize sessions to me.  At first, I may have been a bit skeptical but now I am so glad I found out about Harmonized Brain Centers and would definitely recommend it.  It’s an interesting approach with deliverable results.

Todd Cottle

I have been receiving this therapy, for a while now and it’s been amazing. I have been involved in software design, development, and robotics. This field of profession is really demanding and needs focus thought process.  When I received this therapy, I could not believe the results, it is an excellent scientific way of dealing with the stress and enhance your focus and thus enhance mental potential to do excellent logical jobs, that involve serious decision-making ability and logic.   Sheri is a great person and does have a ton of experience in this field. She is an awesome care giver. On the other hand, Denise at the front desk is awesome too. Denise is a great personality and very helpful. Thank you, Sheri, the results I have achieved after the care you provided is superlative and I recommend this to everybody who wants to improve their quality of life, sleep, and decision-making ability.

Tamojit Chakraborty

I was noticing brain fog and inability to focus not common to me.  So, I went for full sessions and WOW!!!!  balance, emotional stability, functioning restored.  Easy, not painful, and it should be covered by insurance. Worth it. More important than a massage!!!

Rebecca Baker

Me and my family have all done multiple sessions with Sheri and it has been amazing! I was a skeptic at first but after 4 sessions, I have realized how much calmer I am. And I have been reading more books than I ever have. Highly recommend.

Ben Muir

Continue your great work because it is exceptional and a life changer for someone who doesnt realize what life has to offer or doesnt think life can ever get better. My grandson has gone from failing school to getting As and Bs and he has friends now and is happy. Thanks again for changing lives for the better. We will never forget what you have done for our family.

David Crumby

I started seeing Sheri in the throes of severe postpartum depression and anxiety after the birth of my second child. I didn’t know much about LENS Therapy but was willing to try anything at that point. I didn’t notice any major changes in the beginning (and I must admit that my sessions were super inconsistent due to lack of follow through on my end), BUT, after about 4-5 sessions, I realized how much better I was feeling. Like a fog had been lifted. I felt like myself for the first time in almost a year. No more panic attacks, I was sleeping better, laughing again, I could go on and on. It was a gradual lifting over just a short couple of months.

The whole process of LENS Therapy has fascinated me. The treatment is super simple, quick, and painless. Sheri is incredibly kind and exudes a great deal of wisdom and peace. She walks you through every step and educates as she goes. This meant a lot to me, because I’m the type of person who wants to understand what’s going on and feel in control of my body/health.

I would absolutely recommend Harmonized Brain Centers to anyone dealing with emotional/stress/sleep/migraine/attention concerns… to get to the root of the problem and provide lasting answers and relief.

Jackson Sherrill

I went here with the worst anxiety in the world it changed my life.  I would totally suggest this for anyone, my only complaint is that drs. Dont tell you about this!!!!! I LOVE HARMoNIZED BRAIN….Please come see them.

Genia Gilchrist

Sheri and the team are so knowledgeable and delightful! I have tried several different types of neurofeedback over the years, and LENS is by far the most effective and efficient. Absolutely recommend Harmonized Brain Centers Nashville.


I went to Harmonized Brain Centers after doing some research on what might help with anxiety and sleep issues.  Sheri is such a compassionate, caring, and intuitive individual!  She explained the process clearly. My once-a-week treatments lasted for six months, until Sheri and I both felt that I had reached my plateau, and I still go once a month for “tune-ups.”  My anxiety has calmed down, and I have enjoyed significant results with digestive and sleep issues.  I highly recommend Harmonized Brain Centers.  Thank you, Sheri, and Denise!

Gloria Pillow

Loved my experience with Harmonized Brain Centers in Nashville. Sheri was always professional, explained the process in understandable terms, and always talked me through the process so I could understand the whats/hows/whys of what we were doing. It was not physically painful or uncomfortable in any way other than that I felt a little tired afterward (Sheri explained it as feeling like I had a good cry. She says people either get “wired or tired” after their sessions). Since being treated by HBC, I no longer experience daily severe headaches, brain fog, trouble focusing, and sleep problems.  I definitely feel like it was worth going; I would do it again.

Ginger Kirchmyer

A true-life changer! After years of dealing with severe anxiety and depression, I have finally found relief. Sheri is an amazing person and was so kind and helpful during the process. She coached me all the way through, helped me learn new and better way of coping with things and as my brain got better, my life got better. I would recommend this to anyone suffering with anxiety and depression. No more drugs, no more side effects. Just a new and better me!

Sarah Butler

Sheri is extremely competent and produced phenomenal results that allowed for alleviation of my depression. I would highly recommend her services.

Clarke Peyton Carter

This has been an amazing experience for me! After years of suffering with anxiety and depression, I felt hopeless. I found Harmonized Brain Centers through a google search and it has literally changed my life! My depression is gone, my ability to handle stressful situations is so much better and my focus is better than I ever hoped. For the first time in years, I feel like reading for pleasure and I actually retain what I’m reading.

I would recommend this to anyone suffering from anxiety or depression. It is better than any pill, no side effects and talking with Sheri has helped me change lifestyle habits to make my life the best it’s been in years.

Denise Miller

I just completed 10 sessions with Sheri, and I can’t say enough good things about my experience. After 2-3 sessions, I noticed a marked difference in my clarity of thought, and a fog started lifting from my brain that I didn’t even realize existed. 10 sessions were all it took to get all my brain waves flowing correctly again, and I’m done. Brain waves stay corrected unless new trauma, extreme stress, or brain injury occurs. I am now taking my son to help with his attention deficit and after one treatment he states he can tell a difference in his focus already. I am completely happy with my results! A friend recommended me to try her out, and I am grateful. I never met Sheri before I went for my first visit. She was easy to talk to, and asked questions about how I was feeling at every visit. I would highly recommend LENS therapy to anyone who has experienced trauma, head injury, extreme stress, any form of abuse, ADD, ADHD, PTSD, etc.


Sheri has been a blessing to me.  The brain training has brought smiles instead of tears.  Sheri always has a smile and I look forward to the appointments.

Donna Beers-Hill

Sherri is the absolute best in the business!  Love, love, love her!!!

Dave Jackson

From bottom of the class to the top!

“Our 13 year old son was having problems managing his explosive anger, attending school and completing his work there. He was also having trouble managing his personal relationships, both socially and at home.

After treatment at the HBC ‘the fog’ has cleared. It’s like he spent the first 13 years of his life walking around in a fog, I know he thinks more clearly now. He’s a much easier child to be with.”

J Reed

Son-in-law is a different person after LENS Therapy

“My 24 year old son-in-law has just completed a series of LENS treatments at the Harmonized Brain Centers. He is more relaxed, able to have a calm conversation and stay on the subject. He is more thoughtful and genuine in his interactions.”

D Wood

Son-in-law is a different person after LENS Therapy

20 years of depression, after two LENS’ sessions, I’m happy again!!

“Crazy! I’ve suffered from depression for over 2 Decades, I’d lost hope of feeling better. Till I found out about this place, did my research and decided to hope even though I was afraid to. I’m in progress, but after just 2 sessions I feel happy again! I’ve had joy and peace at times, but happy!!!

I’m so thankful for the incredible work they do hear and can’t believe this option of therapy has been around since the 90’s and NONE of my mental health professionals mentioned it, only medication!

So thankful!! Thank you!!!”


Anxiety at a new low

“My deepest thanks and gratitude to Dallas and LENS. Last week my anxiety was an 8/10. I was worried that I would not be able to cope anymore. After the LENS treatment, my anxiety dropped to a low murmur.

I came to Harmonized Brain Centers over a year ago with unexplained anger and complications from childhood trauma. LENS has been a literal life saver helping me to deal with my past without using medication. What a Godsend this treatment has been for me. Thank you!”

D Wood

Anxiety at a new low

Concussion & Panic attacks: After LENS, now coping with life’s challenges

“I sought out help at Harmonized Brain Centers when I suddenly started experiencing panic attacks and explosive anger. Afterward I remembered hearing about LENS while attending a brain injury support group that I was participating in. My symptoms before coming to Harmonized Brain Centers were a delayed onset concussion and depression, anxiety, unexplained anger and panic attacks as a result of child sexual abuse.

I am now doing amazing after my treatment at Harmonized Brain Centers. After the first treatment the anger went away and I have not had another panic attack like I did either. I am able to manage the anxiety and depression in a way I never would have imagined possible.

The biggest change in my life is being able to cope much better with all that life still throws my way. Where I would be knocked down for days in a deep depression, I now only feel a minor disruption in my life.”

Lisa K

Migraines: From several a day to none after just 8 weeks therapy!

“After a couple neurosurgeries in March, 2014, I was experiencing several severe migraine headaches every day. I was told by the surgeon that I was going to have to live with these headaches now as a result of the surgeries. I didn’t like that answer, so I started looking for other alternatives. After a finding only partial relief from the other treatments, I sought out Harmonized Brain Centers.

After the first 5 or 6 treatments, the headaches decreased in severity and frequency. After about the 8th or 9th visit, my headaches were gone.

The coolest things I’ve experienced are seemingly small, but very significant:

After needing a GPS to go just about anywhere (because of memory problems), I no longer need to use it to get around.

My ability to work and be active all day has drastically improved.

Fewer headaches, which are much less severe when I do get them.

I’m able to walk straighter (I had a foot that was very bowed out that now points straight).

My thinking is much quicker, and I’m not struggling to find words like I used to.

I have a lazy eye as a result of some earlier surgeries, and now they track together much better.

My experience at HBC has been literally life-changing. My family and I are so thankful for what you do. You have changed our family for the better.”

PTSD, Depression. After four months with LENS, a huge transformation

“I felt like I was living life in circles. I would read a health book- take that info- and use it, then become depressed. It was an on-going cycle. I needed help getting out of a rut mentally.

My symptoms were anxiety, PTSD, Anger, I couldn’t hold a conversation, didn’t know how to be in a formal setting or even go on dates, I was depressed.

Words can’t express how I feel today. I know how to be a man with integrity again, I can make jokes, I can confidently meet new people and especially women – I’ve been using HBC for 4 months I believe now, and enjoy my sessions.

I now take chances, risk and to keep fighting the good fight that I thought was lost forever.”

J Stephens

Trauma: Car accident victim gets her life back

“I sought out help at Harmonized Brain Centers because I had a traumatic brain injury and had recently gone through a lot of traumatic losses and family turmoil. My symptoms were depression, TBI, anger-memory problems, ADD, and anxiety.

After treatment at Harmonized Brain Centers It made a huge difference to me. Between the treatments and Dallas and Shelly’s loving care, I moved through my issues much faster than I normally would have. It helped the anger and depression a lot. Since I always suffered with clinical depression and have TBI; after a year I could probably use a tune up. I will be forever grateful and am so thrilled this treatment is out there to help others who suffer.

It helped my brain to relax. It moved me towards forgiveness and joy. I became more “myself” than I had felt since my car accident 9 years ago…more social, happier. It has helped a lot of my friends towards recovery and a better life.”
