I have been under Dr Nemanich’s care so nice I was 45 (66 today) when he tossed a couple of stents in for me. Another stent 10 years later and good to go. He takes all the time I need w me, answers all questions. Highly recommend him and his welcoming staff.

I was a patient of Dr. Nemanich for three years prior to March 2014. At that time he told me that my aortic valve would last for about six months but he would not do surgery. I lived with the idea that I had only six months to live. I was in severe pain when I went to another cardiologist in 11/2014. He suggested I see this excellent surgeon. I had open heart surgery on 12/2/2014. I had no problems and was told I had strong heart muscles. I am now 93 years old, no thank to this doctor.
