Providers at this office were always polite and showed concern at all times. I was welcomed by a friendly greeting upon entering. I saw dr. Nienabor within a few minutes and was impressed by his appropriate and accurate response to my problem. In addition he was caring and reassuring which helped me a great deal in a stressful situation. He is one of the best physicians I have ever seen.

As always Dr. Nienaber listened to my concerns regarding varicose veins on my legs, he explained about the ones on my legs + referred me to Vascular Surgeons that he said are very good at what they do. His confidence always helps take concerns away -- he's a good doctor because when you leave his office you know that all w/b well.

He is an awesome doctor. I mentioned a wrist problem and he showed me how a palm massage can help it. Felt so good. I've been doing it before I exercise which has been helpful. Love Dr Nenebor.
