Dr. Hammer is an outstanding ophthalmologist. He is highly knowledgeable, extremely detail-oriented, and very professional in every aspect of his work. He takes the time to listen carefully, explain everything clearly, and answer questions with patience and expertise.
What impressed me most was his ability to build trust and confidence. He has an excellent bedside manner and makes patients feel comfortable, respected, and well cared for. His professionalism, attention to detail, and genuine concern for his patients truly set him apart.
I am very satisfied with the care I received and would highly recommend Dr. Hammer to anyone seeking an exceptional eye doctor.
Thank you, Dr. Hammer, for your excellent care and dedication to your patients.

My children and I have been visiting Visionary Eye Doctors since 2014 and we come back every year for our eye exams.
Lorena Rivero and Babak Hosseini are both wonderful—very professional, kind, and thorough. We always have a great experience. Highly recommend!

The doctors are great. The reception area is chaos. You’ll not get seen at your scheduled time. This practice specializes in people with eye issues. Things I saw today. Assistants come in the waiting room asking for patients by name. No one can hear them over the noise. Giving a blind person a form to fill in 😂. Giving a low vision person forms to fill in that’s hardly legible by normal people. Patients skew older. Assistants skew very young. Results are entirely predictable.

3000+ reviews should be a red flag in itself. Was here a couple years ago and never plan to go back. This practice treats patients like cattle to be herded through different stations. My appointment took hours and though I appreciated the thoroughness, most of the diagnostics that were done seemed to be more for their records and benefit of billing than to actually help me because I got very little explanation. I didn’t feel I received any personalized care here. Even when I finally saw the doctor, I was talked to like someone who has x and y and given a disorganized sheet of paper with a bunch of recommendations crammed into it. My previous ophthalmology appointment before moving to the state was just me and my ophthalmologist, who took the time and effort to learn about my situation and discuss the ins and outs of the options that could work for me

Great office. Superb doctors and fine tech staff. I recommend them highly. (Especially Dr. Medina). It’s a very busy office, but they move folks along very nicely. It’s worth waiting for quality.
