What Our Patients Are Saying

5 stars

"Went to TriCounty Eye Institute to get my yearly eye exam, which I admit I don't do as often as I should, and I couldn't be happier with my choice to go there. All the staff was great throughout the whole process and Nancy was exceptional at being patient with me while I tried on a million glasses till I found some I liked. I would definitely recommend to others. I also took a family member there on a more recent occasion and they also were attended with the same great level professionalism I expect from TriCounty."

"I’m so grateful that Dr. Schneider did LASIK surgery on my both eyes 8 years ago. He is a professional and did a great job. I used to wear glasses, but since I did LASIK surgery in their facility I didn’t wear glasses. Even after these long time passed, I don’t need to wear glasses anymore. By correcting my vision, he made a life more beautiful for me."

"Tri-County never lets me down! All of the doctors have always been so helpful and quick. The staff is so friendly, I feel like I'm with family while I'm there. Becki is always a pleasure to interact with and helps my family and me find just the right pair of glasses every time. Thank you for all that you guys do."
