I had such a great experience with this ophthalmologist. From the moment I walked in, I felt listened to, cared for, and truly valued as a patient. They took the time to explain everything clearly, answer all my questions, and make sure I was completely comfortable. The exam was thorough, the treatment plan was easy to understand, and the entire staff was friendly and professional.
It’s rare to find someone who is not only highly skilled but also genuinely compassionate. I left feeling confident and well cared for. I highly recommend them to anyone needing eye care—you’ll be in excellent hands!
