Dr. Rumamcik is an amazing nephrologist. He never gives up. It took him two years to get my BP under control and my kidneys in great shape. Thank you Dr Rumamcik.

I am a registered nurse and have been patient of, or interacted and worked with hundreds of doctors over the years. Dr. Rumancik is top ten material in my book! Love him! The appointments overall can take a lot of time. But rest assured that it is because he takes his time with all his patients and is extraordinarily thorough. He will make sure you get in to see him if he feels it is necessary. Once he came in on a vacation day for me when he was concerned about my lab results. I have extremely rare conditions and he was very knowledgeable. What he didn't know, he took the time to read about. But my guess is he didn't need to read up about very much! He is brilliant. I trust his judgment unwaveringly. He makes sure he gets a diagnosis and doesn't leave you in limbo. And he is willing to order any labs and tests to get answers for his patients. He is the best, hands down. I am lucky to have him on my team!

He’s rude and cold to staff. Talks down to people, and tries to be intimidating to the staff he works around.
