After suffering a Traumatic Brain Injury for 8 years and trying everything, I am finally seeing steady improvements in the last 8 months since seeing Dr. Zelinsky. I literally have been to 40 doctors and 40 complementary healing modalities and so few have really helped. If you want your life back, you owe it to yourself to try this! It works. I wish I had done it sooner, but could not drive or figure out how to get there. A simple flight and Lyft/Uber make that easy now, so don't let that stop you. I am so grateful for her brilliance and her work! She is a godsend. -The TBI Coach

Like so many others, I was immensely fortunate to have found Dr. Zelinsky by reading The Ghost in My Brain book (by Dr. Clark Elliott). After months of desperate scrambling, going to doctor after doctor seeking help with my debilitating concussion, Dr. Zelinsky was able to quickly identify my hidden visual concerns and address them. She has been compassionate and understanding and provided effective solutions using therapeutic eyeglasses for my head injury. Thank you Dr. Zelinsky for giving me my life back, there are few words to express how appreciative I and my family are for your amazing work!

I have been taking my son Grant to mind eye connection for 10 years! Yes, 10 years and I am still truly amazed at how her techniques and bell test still help my son with his auditory processing disorder. She is ahead of her time and finally after 25 years of research she has done, the US doctors are now inquiring about her bell test. I found a gem in Dr. Zelinsky, she is amazing and has made my son's academic experience a positive one. So worth going to see this doctor, you will not regret it.

I am amazed by Dr. Zelinsky - seriously amazed. I am dealing with post concussive symptoms (1 year out) including difficulty with sensory integration.

Her Z-Bell test is mind blowing. I don't get it, but I don't need to. All I know is that I have been wearing lenses for 4 weeks now and the impact has been staggering. I wish I had come to see her sooner and am excited for my next set of lenses.

If you have a TBI or PCS, save your $ and see Dr. Zelinsky. I am so grateful I decided to after putting it off for several months. I have tried several other therapies: including vision with a Neuro-optometrist and NUCCA (upper cervical chiro) and these lenses have yielded the best results. Hands down.

How do you properly thank someone who has literally given you your life back... She is so happy with my recovery, and I am forever in her debt for helping me regain full functioning... Do the people you care about a favor - if you know anyone that has suffered a brain injury, give them Dr. Z's information. She is absolutely worth the time, travel, and money. I wouldn't have the job I have today, be running my ministry, or enjoying life if it wasn't for Dr. Z, whom God has gifted with brilliance, innovative treatment methods, and a wonderful, warm, caring heart for each and every one of her patients. People are coming from all over the world to see her, because she gets results.

Yes, she is one of those rare people who is in fact, that good. #gratitude #drzrocks

Dr. Zelinsky, thank you for resolving my vision issues that I sustained as a result of my TBI. You confirmed my symptoms and gave me the confidence that I would heal. You predicted I'd be better in 6 months and you were right on, I continue to improve everyday thanks to you.

Dr. Zelinsky was able to help my daughter when she was very young with her eye problem where no-one at the time could even diagnose what was wrong with her. My daughter excelled in school and her eyesight just got better and better. I have recommended this place to everyone I know who has an unsolved eye problem. Dr. Zelinsky's patience and personality made it such an enjoyable experience for my daughter.

Much, much more than "just an eye doctor." Dr. Z has a solid practice in eyes but for anyone who personally struggles with spectrum related issues or who has a child that struggles with autistic spectrum issues, Dr. Z is a godsend. Her innovative and deeply researched approach has produced amazing results for many families. I Highly recommend this practice. It is true that the doctor has struggled with some of her help in the past, but she has made major strides in this area and we have had great service in our basic eye care, glasses, and eye therapy. Definitely worth a visit!

Doctor Z has saved my life multiple times. She cured me of my post concussive symptoms. I rate the Mind-Eye Connection 5 stars and would recommend it to anyone.

For the first time in my adult life I can see well with glasses. Dr. Zelinsky and and Dr. Wright did this cool test in which I closed my eyes and tried to touch a bell that they rang. I couldn't touch it... Until they covered my closed eye with a red tented lens. Then my hand went right to the bell... with my eyes closed! It's crazy! Then, Dr. Zelinsky did the same thing with my daughter. Our minds, eyes, and ears are indeed connected.

The Doctor is off the charts brilliant. When my kids were having challenges in reading and school work . She understands how the brain works and the connection of the visual connections like no other. Amazing results.

Ann R. - from yelp

Our daughter had a great deal of difficulty learning how to read and wore prescription glasses. Several people suggested vision therapy and we took her to two different doctors for an evaluation. She has been seeing Dr. Zelinsky for almost a year. During that time Dr. Zelinsky has made several changes in our daughter's prescription glasses, which has resulted in incredible progress in her ability to read with greater ease. We are very pleased with this progress and look forward to continuing to work with Dr. Zelinsky.

The Penner Family - from Northbrook, IL

"In our daughter's own words she says, 'Dr. Zelinsky has blown my mind away with the amazing things she has done. I have noticed such a difference!' Simply put - you have made a difference in our child's life and we can't thank you enough!"
