Dear Dr. Zangler, I would like to thank you for your excellent eye care services, very professional and friendly. Also, congratulate Danielle for the outstanding service she provided to me. The BlephEx treatment was very effective and my symptoms improved immediately. Thank you for your dedication to your patients and your excellent services!!

Not long after my granddaughter started playing piano her teacher was concerned that she might be experiencing some vision problems. Of course, I wanted to address this right away. But not all clinics offer vision therapy. It is even more difficult to find a clinic that has advanced training in pediatrics. Happily, we were referred to Brenart Eye Clinic for an evaluation. They have it all! I can’t say enough about the sensitivity, skill, and knowledge of Dr. Tonya Tira (who has specialized training in pediatric vision problems) and the vision therapist, Ashley Meyer. They identified a number of issues and developed a customized vision therapy program for Mackenzie. Today, Mackenzie’s vision problems have been corrected. She no longer suffers with headaches and her vision is within normal limits. I truly believe that Brenart Eye Clinic helped Mackenzie overcome problems that could have affected her studies, music, career and self-confidence for the rest of her life. Thank you Brenart!

The song "I can see clearly now…" was in my head as I left today. This was my second visit to Brenart. I found this office by polling the 60+ people I work with, and Brenart Eye Clinic was recommended the most.

My long-time eye doc retired and I went to Brenart based on a friend’s recommendation. Office is great, doctor was friendly and knowledgeable.

This is by far is the most beautiful eye clinic that I have ever visited and they are extremely professionally staffed and they are very very efficient and quick. I would recommend them to anyone who is seeking real optometric attention and truly there is not much difference pricewise between them and any of the big box so-called clinics. And their selection is far superior if you were looking for stylish eyewear. I would recommend nowhere else to go for all of your needs related to vision care!

Great service. Always get my prescription perfect. I drive all the way from Arlington Heights to come here and it is totally worth it.

I would not hesitate for one second to tell you to run, don’t walk, run to see Dr. Nicole Zangler if you are having any problems with your vision. One quick phone call and she has worked out a game plan and completely set my mind at ease.
