What Our Patients Are Saying

I’ve been going to Dr. Esther Ahn for over and her clinic provides the best customer service. They carefully make sure that glasses/contacts are comfortable and fit perfectly.

Their handling of COVID-19 has been splendid also. They follow the health instructions strictly so that your health and theirs are safe. Please have patience scheduling appointments with them during this time as it appears they can’t take as many patients in a day as before.”

I went to doctor Ahn for more than 10 years, she always provide the best service you ever can get ! customer satisfaction it’s Always 😀😃😄

Linda L

I have been going to Dr. Ahn since I was a child. This office has always been welcoming. Just went in for my annual checkup post COVID and I am very impressed! They schedule only one patient per hour and to ensure their staff safety they have a health questionnaire and do a temperature check upon arrival. Per Dr. Ahn they rotate their staff and their doctors to ensure just in case someone gets sick it doesn’t affect their whole staff. As a healthcare worker myself, I appreciate what precautions have been put in place! Thank you Dr. Ahn!!”

Clare F

I started going here this last year to get glasses and the staff is beyond friendly and super helpful! Specifically, Sam P. has helped with choosing and ordering my new glasses every time; he’s extremely patient with answering all my questions about insurance, frames, and pricing so I always know exactly what I’m getting and paying for. Would highly recommend this optometry!
