Dr Kietz took time to make our daughter feel comfortable at the appt. He talked with her and showed genuine interest in her. He was very friendly and took time to answer all of our questions. He is very knowledgeable about his profession and very approachable. We are very happy to be seeing Dr Kietz.

Dr Kietz is one of the best Drs I have met

July 18, 2017

I love Dr. Kietz as my doctor that's why I travel two hours to see him instead of finding someone closer.

Dr. K is the best and we are very happy with the care be has provided in the past 6 years.

Dr. Kietz is a remarkable listener and very empathetic to our son's condition. He directed questions and conversation to our son which is unusual in pediatrics. This way he got our son's perspective first-hand. He spent as much time with our family as needed and addressed all of our concerns.

July 03, 2017

Dr. Kietz is not only clearly an excellent doctor but he obviously cares about his patients and takes time to listen and answer questions from my daughter and myself, we are lucky to have him.

July 03, 2017

While it requires taking a day off work for these appointments, I know my son is receiving the best care. Finding Dr. Kietz and this Health System was the best thing for his care. Thank you, thank you, thank you!
