The reviews listed below were collected independently of Unio Specialty Care through rater8. Each review represents an authentic and verified patient experience.
As a long time, Patient, it’s always a wonderful pleasant experience when having a in person appointment with Dr. Garrett Matsunaga words can express what a great doctor. He is caring, humble, and very easy to talk to especially if you have any questions he will explain them to you in detail. Today my visit explained a new surgical procedure for my enlarged prostate and put me at ease by his explanation of the procedure and I look forward to having the procedure done to improve my symptoms so I can have good quality of life.
