Dr. Kietz listens well and helps provide suggestion for my health as well as acknowledges my suggestions (specifically requesting to go back to physical therapy).the nurse that has been there for all of my appointments have the most amazing "bedside" manner!

Dr. Kietz is a phenomenal physician and we look forward to seeing him each time. He has a standard of excellence.

Dr Kietz is an amazing doctor. He always speaks to our 2yr old daughter who is the patient, which in turn makes her feel very comfortable with him. He never makes us feel rushed and always answers our questions. We may wait a little extra but I never mind because I know he's giving other patients the time they deserve. I fully trust Dr Kietz and would recommend him to anyone!

Knowledgeable. Engaged. Fun. Effective communication. Did not feel like a "number" or rushed.

Dr. Kietz is an extraordinary physician. He understood my son in ways that no other physician has before, both physically and emotionally. His listening skills, bedside manner, compassion, and knowledge are outstanding. He provided insights into my son's medical history and prior treatments that were life changing for our family.

As always, Dr. Kietz is the best doctor I have ever come across. I have five children and have seen many doctors over the years, and he is the most empathetic human being. My son loves going to see him and feels the same.
