Couldn't have been more pleased with the Doctor's care, questions and answers. Very concerned with what I had to say. He told me what testing was needed and hopefully find what the problem is so he can get started with a solution. I had prayed that I would get the doctor I needed and my prayers were answered.

Dr. Simpfendorfer is outstanding is the way he listens and pays attention to me as an individual. He takes time needed to get to know me in the context of my whole life. He also takes time from documentation to sit back and look me in the eye. He also has an outstanding sense of humor, which he uses very effectively to foster the therapeutic relationship with me.

Reviewed on Aug 31, 2023

Dr. Conrad Simpfendorfer has treated me for over 30 years and he is extremely knowledgeable and caring. He was involved with my care requiring stress tests every other year to check my condition after a very minor heart attack when I was 40, when I was passed off from another interventional cardiologist at Fairview Hospital who was retiring. After 3-4 stress tests he did a necessary catheterization to determine 4 blockages in the heart. He got me to a talented surgeon team at CC for a quad by-pass 20 years ago. He has been following up w/carotid screening and stress tests/blood work ever since. When I developed atrial flutter, he got me to Dr. Bhargava who handled that successfully. I have been so lucky to have known Conrad and his associates over the years.
