Dr Mahoney is an expert eye surgeon. About 5 years ago he repaired an unsatisfactory prior operation on my left eye by another surgeon. Now he will be doing a similar corrective procedure on my right eye. The outcome of the prior surgery on my left eye was very successful. There was no question in my mind that I should return to Dr. Mahoney when the other doctors work on the right eye began to fail.

Dr. Mahoney is a excellent physician.
- 5 out of 5 starsReviewed on 6/17/2025
Only thing I would ask is for Dr Mahoney to introduce himself when he enters the room. He looked young (compliment) and was dressed casual (which was nice) and I had to ask if he is the doctor. Otherwise everything was explained briefly (which is fine for someone who is cognitively intact), and done efficiently. He was patient with my questions and I appreciate the validation of my ability to tolerate the procedure of the needle in my tear ducts with saline flush. I appreciate the referral to the dry eye doctor when no blockages were found.
