The reviews listed below were collected independently of Unio Specialty Care through rater8. Each review represents an authentic and verified patient experience.
Good attitude towards the patient, he explained the procedure to make it understandable to the patient, the only thing was when he tried to explain why using AI as an assistant to his own examination , it made me feel a bit uncomfortable as whether the doctor knows what to look for or AI is to really do it for him, otherwise he was very kind and professional.

He really took his time with me today. He approached all of my concerns with empathy and clarity. He did not make me feel self conscious about asking the many, many questions that I had. Basically he put my mind at ease. I feel we had a clear plan for the beginning of my new medicine moving forward.
