Dr Friedman is excellent in every way. I became his patient after a terrible experience with another glaucoma doctor at the Massachusetts Eye and Ear. [redacted]


February 2025

Dr. Friedman was terrific. He addressed all of my needs. He worked in close conjunction with my primary provider, Dr. [redacted]. He made himself available because I needed this procedure quickly and he made it happen and he did it in an exceptional way. I couldn't be any happier.

Dr. Friedman is obviously extremely knowledgeable, but also has the ability to explain things to his patients in an understandable way. He has a wonderful demeanor and is someone who I would highly recommend to friends and family.
