The reviews listed below were collected independently of Southern Oregon Cardiology through rater8. Each review represents an authentic and verified patient experience.
My consultation with Dr. Giesen was much more than I expected. I had never needed a cardiologist before and was nervous but he quickly put me at ease, explained the upcoming tests and discussed a possible medication ( which was initially refused by my insurance but then almost immediately approved). I feel that I am in very good hands now.
