I have been going to Dr. Blackman for 8 years. First for thyroid & then he was the only doctor in 9 years to discover I had Primary Hyperaldosternoism. Got me into the Mayo in MN. He is brilliant, caring, patient, thorough and always willing to listen to my medical concerns & questions. He is by far my most favorite physician ever.

Dr. Blackman is the best Physician I have ever had. He is patient, an active listener, and makes me feel like I am involved in my own treatment. His bedside manner is amazing. I wish all physicians treated their patients the way he does.

Let's talk about my long journey as Dr. Blackman's patient. I have seen Dr. Blackman for over seven years now and have been trying to be treated for Hashimoto's. Dr. Blackmans is a nice person, yes, but he has failed me in more ways than I could ever imagine. The only thing that he cares about is my TSH and T4 levels and outside of that he has no concern for anything else. His nurse Terie is incredibly disrespectful and has actually laughed at my concerns before.
