March 13, 2026Diana G.Verified patient
First time visiting an optometrist, I was immediately put at ease and all my questions answered. I ended up seeing a different optometrist than I initially scheduled, but I was informed in advance and the office staff were incredibly accommodating with my schedule and any concerns. Lastly, it's easy enough to find parking and very convenient location if you have other errands before or after your appointment.

I have seen many eye doctors and Dr. Ma really stands out. Extremely detail oriented and extremely thorough. Really, really! Office staff is fantastic and the attention to detail and knowledge base of Dr. Ma is pretty amazing. Never had an eye appointment like this one before. If you are needing a great doc, go see him.

Dr. Benjamin Na was excellent. He was straightforward, asked detailed questions, and made sure I received the right treatment for my eye needs. His staff was very friendly, helpful, and informative. I felt very comfortable throughout the visit, especially since it was my first time there. I highly recommend his office for anyone seeking quality eye care.
December 10, 2025rustico M.Verified patient
Dr. Na was so helpful and was the first Dr. to tell me that i probably needed semi focal lens since i was a kid. My mind was blown and I almost cried upon realization after wearing semi focal contact lens that my eyes were supposed to feel “this relaxed” when reading. Thank you, Dr. Na!
October 30, 2025Pamela P.Verified patient
The staff listened to my concerns and I appreciated that Dr. Na is competent, concerned, and thorough. It was an excellent visit.
