I really like Dr. Riva- I always feel very free to ask questions or ask for clarification. He’s very kind & thorough. I come away knowing what I need to know about all that we have discussed. Amber, his nurse, is a great asset to the doctor. She’s very friendly & fun to chat with, yet very focused on her job. If I was a nervous person (which I’m not) her soothing demeanor would help to prepare for seeing the doctor.

Dr Rivadenyra is always friendly and concerned about my health. He is easy to talk with, answering any questions I might have. It's nice that he is so up to date on new and promising medications for treating diabetes. He takes the time to explain how the work and why they could be a better fit for me.

I had my first visit with Dr. Rivadinera this morning. I was needing to transfer from a physician in Urbandale, who had been an excellent physician, but I had decided to not to drive out of town when, if possible after this. Dr. Rivadinera was more than met my expectations. He was a good listener. He went over my history with me very carefully. And sat down, look, me in the face and explained a number of things relating to side effects of treatment and seemed sincerely to went to answer my questions about about those things. I really appreciated his attitude and his manner. I will be seeing him again to follow up with my treatment.
