Dr. Nielsen is an exceptional physician. He takes his time, explains test results and you have a plan when you leave. I left with all questions answered and felt like I was in the best hands possible, no anxiety. I feel fortunate to have been referred to him!

Very polite. Even though my mom has dementia, he talked to her instead of me. I greatly appreciate that. Highly recommended

This was my first time seeing Dr. Nielsen and he was so easy to talk to and ask questions. He was thorough, wrote everything down for me to take home, and explained everything to me, which I had never had anyone in six years do. The staff were all wonderful as well. I highly recommend Dr. Nielsen.

Dr. Nielsen as gone above and beyond to find out what was going on with me. It took him looking into my past doctor visits, to different doctors, to find I had some symptoms going back many years. He caught what no one else had. I enjoy my visits, he never leaves before I have all my questions asked. He takes his time with me and gives me written information if I need it.

I’ve been a patient of Dr. Nielsen for years for CKD. I’ve always been treated very well by both Dr. and his nurse. Dr. takes time and explains everything throughly and I always leave there reassured that I am getting great care
