    I have been visiting Dr. NIck Mamalis for years. He took care of my cataract surgery and its aftermath. He has been a pleasure to visit and I feel well taken care of.

    August 24, 2023

    Excellent. Great explanations

    August 23, 2023

    As I said, once the assistant was done with me I sat in the damn room for about an hour before the doctor got to the room. That was way too long.
