Patient Comments
Patient comments are gathered from our patient experience survey and displayed in their entirety.
Patients are de-identified for confidentiality and patient privacy.September 27, 2024MORAN EYE CENTERDr. Mamalis was very thoughtful in his responses to my questions. He listened carefully and offered recommendations based on evidence. He was also clear on where there was professional uncertainty regarding the causes of certain issues.
September 27, 2024MORAN EYE CENTEROne of the most knowledgeable and professional doctors the ÈËÆÞÖгöÊÓƵ has.
September 25, 2024MORAN EYE CENTERMy mother in law is a patient of Dr. Mamalis. Over the last 6 years I have taken her to see him, I knew I wanted him to become my doctor as my eyesight changed. He is honest and thoughtful with his explanations and diagnosis. Dr. Mamalis does not pressure you to make a decision, he carefully explains the choice is up to the patient.
September 25, 2024MORAN EYE CENTERDr Mamalis explains everything he's doing as he's doing it.
September 24, 2024MORAN EYE CENTERLove him he's a great Doctor.
September 19, 2024MORAN EYE CENTERAttentive care. Glad I saw him.
September 18, 2024MORAN EYE CENTERDr. Nick Mamalis is a kind and considerate doctor. He listens to my questions and concerns. He also explains what he is doing during the exam.
September 18, 2024MORAN EYE CENTERI know Dr. Mamalis from 2005, when he was a consultant for a drug delivery project. He was like a teacher to us and always explained every detail on what he observed on our experimental samples. He has been my eye care doctor for a long time. I am very happy to have him as my eye care specialist. He is very caring, patient with my questions and has been very clear in explanations. I would gladly suggest Dr. Mamalis to any of my friends.
September 17, 2024MORAN EYE CENTERDr. Mammalis was thorough, quick, friendly, and caring
