Review of Dr. Duncan

- |

Our daughter was blessed to receive Dr. Duncan’s care when she was 6 months old. He had moved to Omaha just months earlier from, I believe, Canada. Our daughter is now 26 this year, married, and has two healthy small children of her own. I was looking up to see if Doctor was still in Nebraska, and when I saw him, it brought me to tears of joy and gratefulness. This man had the best bedside manner, for two parents that were so afraid. He took wonderful care of our daughter. If you need a doctor you can trust, this is your doctor.

Review of Dr. Um

- in Hinton Iowa |

Dr. John Um performed two surgeries on me, In 2013 he placed an Lvad in my chest and 6 months later (2014) performed heart transplantation. Dr. Um is compassionate, knowledgeable thorough, totally competent and very approachable. At all times he was available to.answer my questions and provided answers that I could understand. If there was a way to give him 50 stars I would do it. He saved my life, I am very healthy.
