“I had a great experience, Dr. K. Nahornyak was very professional, attentive and gave me a lot of information that made me feel a lot better and reassured. She prescribed eye drops that corrected the problem within 2 days. All assistant staff were also very nice and professional. Going back for a follow up appointment next week and looking forward to it!”
