Dr. Mammen is the only physician I would consider seeing for my eye care.

May 11, 2017

was very behind in his schedule never apologized for running late. rushed my eye exam and seemed very perplexed and didn't even ask if I had any questions. I was not very happy...but will give him another chance. :(

I thought that the visit went very well and all seemed to know what they were doing.

This was an initial emergency visit with this provider which is why he did not have my records and a few of the questions were difficult to answer as they assume he was my current treating physician. Although doctor did not have my records, he permit me to give him an exhaustive history. Super nice doctor and I have alot of confidence moving forward. Very happy!
