The reviews listed below were collected independently of Unio Specialty Care through rater8. Each review represents an authentic and verified patient experience.

Mark listened to my questions and responded in easy to understand answers to what the issue was, what possible effects it could have and what the different approaches could be taken and its effects. I asked him what his opinion was and which was the better approach and why. He responded and gave his reasons why. You can’t ask for anything better from your doctor. Her was great..
