OUR PATIENT REVIEWS

Was dining at a near by restaurant before heading to airport to fly home, when my lens fell out of my frame. I walked into the Colorado Eye Gallery and they fixed my glasses at no charge. I can’t express how thankful I am for their kindness. If you live in the Broomfield area go see them!! Thank you again!

Dr. Alper is great! She’s professional, highly knowledgeable and worked with me on getting the right prescription for working on my computer. Colorado Eye Gallery is my go-to for exams. I haven’t gotten glasses from them but I will this time. Highly recommend!

Drs. Gurpreet and Jerry Lucas are very knowledgeable and spend time getting to know you and your eye health needs. Their staff is patient, supportive and kind. I worked with Dennis in choosing the right fit and style of eyeglasses and he was so patient and resourceful in making my glasses fit just right. A truly professional Staff!
